I still think that if Nelson can get the weight of their slide closer to the 8.1 ounces of the OEM slide before an optic is mounted the better it will be. I also think they should use the RMSc footprint instead of the RMR footprint. The Swampfox Optics Sentinel is 0.6 ounces and the Sig Romeo Zero is listed at 0.4 ounces. both are about half the weight of most RMR type optics.

I can't imagine Jeremy offering any footprint instead of the Trijicon RMR footprint ... possibly a footprint in addition to the Trijicon RMR footprint.

I'd expect the next 44X footprint to be MOS (assuming it's not patented) or a proprietary optic system like Agency Arms' AOS (which is actually superior to MOS). With the MRDS attaching to the breech block, I would think the depth of the AOS cut (which is deeper than the Trijicon RMR footprint) would be less of a concern.

I would think if your G19 is RMR-cut, you'd want your G44X RMR-cut. If your G19 is MOS-cut, you'd want your G44X MOS-cut. I want my G44X set up exactly like my G19's.

I'm expecting an update on the gen2 breech block and the gen1 44X slides early this week.

 

[wickedbeernut]

Tim Eliopoulos (Owner of Delta Strategic) posted to the Glock Elite Facebook group that Jeremy installed a gen2 breech block in his gen1 44X slide. He said it runs "like a damn top" / "flawlessly" (with a suppressor).

Originally, Jeremy had said the gen2 breech block wasn't compatible with the gen1 slide. Apparently, he's got it to fit.

I haven't decided if I will give Nelson another try or not after how things went when I asked for an update on my slide. Jeremy was a bit rude at that time.

The biggest hurdle in my opinion is that Nelson needs to get the slide weight minus any optic as close to the OEM weight as possible. With any rimfire pistol using a reciprocating slide, every tenth of an ounce matters. If they can get the weight down to the 801-8.5 ounces that the OEM slide weighs, I might give them another try. I love how the OEM G44 slide runs on my Lone Wolf Freedom Wolf 80% frame, plus it fits my hands better than the OEM frame.

I'm trying to get Tim to weigh his gen1 44X slide with the gen2 breech block. We should be able to adjust for the threaded barrel and Trijicon RMR and approximate the weight savings from the gen2 breech block.

 

[wickedbeernut]

According to my Slide Weight Chart, a gen1 44X slide with Manufacturing Information Marking and a Trijicon type 2 RMR should weigh 10.5 ounces. It would appear the gen2 breech block shaves off approximately 1.2 ounces. I've asked Jeremy just to weigh the gen1 and gen2 breech block.

 

[CBTENGR]

I had the 44X Carry slide and a Swampfox Kingslayer mounted on it. The total weight according to my scales was 10.7 ounces. The Kingslayer with battery and mounting screws is 1.4 ounces.

And the reason I even mentioned using the RMSc footprint is that the optic for that are a lot lighter. Though using a RMR to RMSc adapter would negate any weight savings. The Sig Romeo Zero with battery and mounting screws is 0.45 ounces and the Swampfox Kingslayer is 0.65 ounces with battery and screws.

I know the weight makes a big difference. I tried running the Swampfox Kingslayer and a knockoff RMR (1.1 ounces) on my Keltec PMR 30 using an aluminum mount. Both optics would cause the pistol to not function once it got dirty due to the extra weight. Going with a polymer mount and the Sig Romeo Zero took care of any issues with the PMR30 not wanting to run when dirty. Total weight of the Romeo Zero and Lakeline LLC mount is 0.6 ounces.

My kitchen scale is pretty close to the postal scale Jeremy used when weighing the OEM slide. I got 8.1 ounces for my OEM slide.

Like I said before, every tenth of an ounce matters when it comes to rimfire pistols. Both my G44 and Keltec PMR30 have shown that to be true. The closer the Nelson slide is to the OEM in weight before an optic is mounted the better.

Glock 44X gen1 Diagnostics
​

This Johnny Glocks YouTube video was brought to my attention by a fellow gen1 44X slide owner. Johnny touches on many of the modifications to the gen1 44X slide we've trialed in this thread (e.g., hacked / lighter OEM G44 recoil spring assembly, lighter firing pin spring, ...) and then some.

Let's hope the gen2 breech block (and the gen2 slides in general) will alleviate the need for these hacks.

If you are looking to shave as much weight as you can:

RMR RM06 Type 2 = 34.02g
RMR cc = 28.35g

The RMR cc is almost 4 grams lighter than the RMR and it is still a Trijicon.

I know the mounting footprint is different so I would like to see it offered as an option.

For anyone thinking that 4 grams is not anything:
- When dealing with small aluminum parts you take off what you can where can
- It is reciprocating weight at the rear of the slide
- It is 4g less without any potential reliability issues

Add is some titanium mounting screws like Agency does and there is a tiny bit less.

 

[CBTENGR]

The Swampfox Sentinel and Sig Romeo Zero which use the RMSc footprint are even lighter than the Trijicon RMR cc.

Swampfox Sentinel w/battery and screws - 0.65ounces or 18.43 grams
Sig Romeo Zero w/battery and screws - 0.45 ounces or 12.76 grams

The Holosun 407K and 507K are listed at 1 ounce or 38.35 grams.

I still say that using the RMSc footprint (no adaptors) along with either the Swampfox Sentinel or Sig Romeo Zero is the best way to go to keep the weight to a minimum.

 

[wickedbeernut]

I maintain a post with NPM / BMC 44X customer-requested MRDS footprints,

Breech Block, RMR Cut and MRDS​

The post currently includes Trijicon RMR rear iron sight forward, Trijicon RMR race cut, no MRDS cut, Glock MOS and Agency Arms AOS. I've updated the post to include Trijicon RMRcc and Shield RMSc.

Is the Shield RMS and RMSc footprint the same? It's my understanding the hole pattern is the same.

 

[CBTENGR]

All the information that I can find states that the RMS and RMSc is the same as far as mounting footprint. The difference is that the RMSc optics are narrower for the slim line pistols.

The RMSc footprint and either a Swampfox Sentinel or Sig Romeo Zero are the way to go for any rimfire pistol with reciprocating slide in my opinion. I know going with the Romeo Zero made a big difference with the reliability of my PMR30 with an optic mounted to the slide.

Happy Cinco de Mayo!

Today is the day the Nelson Precision Manufacturing 44X gen2 slides ship! Did anyone preorder a gen2 slide?

Of course, we've been documenting the Nelson Precision Manufacturing and BoogeyMan Customs 44X gen1 slides in this thread for over eight months. If you take a minute to skim through the first post in this thread, I think you'll find we've managed to assemble a wealth of information. I'm hoping members will share their experience with the gen2 slides on this thread so that we can continue to consolidate and grow this valuable database.

On February 1, Jeremy Nelson said gen1 customers would be able to trade in their slide for a gen2 slide (or possibly retrofit their slide with the lighter gen2 breech block). At the time, Jeremy said, "All gen1 customers will be receiving an email from us (Jeremy and his dad, Jeff) soon." I don't see where I've received an E-mail in the last three months. Now that the gen2 slides are shipping, hopefully we'll be hearing from Jeremy and Jeff soon.

Happy Cinco de Mayo!

Today is the day the Nelson Precision Manufacturing 44X gen2 slides ship! Did anyone preorder a gen2 slide?

Are they really shipping today?

I ordered one in December.



Edit: Never mind. I see now that this is the date they are supposed to ship.

 

[wickedbeernut]

It dawned on me that I have the exact same NPM 44X slide (with a gen1 breech block) and Trijicon type 2 RMR that Jeremy weighed above (with a gen2 breech block). My slide weighed 10.6 oz on my cheap digital postal scale. Note that my Slide Weight Chart above projected the weight to be 10.5 oz ... pretty darn close! So it would appear that Jeremy has been able to shave approximately 1.3 oz off the weight of the breech block.

 

[wickedbeernut]

Are they really shipping today?

I'm pretty sure today is the day. The Cinco de Mayo date has been discussed (recently) with Jeremy on several forums including the Glock Elite Facebook group and Jeremy's own Nelson Precision Manufacturing Facebook page. His web site still states Cinco de Mayo. I'm confident Jeremy would've updated us had the ship date changed. Keep an eye out for that ship notification!

Déjà vu all over again.

NPM and BMC started accepting 44X gen1 slide pre-orders on September 7 (Labor Day) 2020. The BMC slides were to start shipping on October 15. The NPM slides were to start shipping on October 31. The NPM and BMC slides actually started shipping on November 11. Pre-order customers started receiving their slides on November 16. Of course, there were finish and fitment issues. NPM and BMC E-mailed all of the pre-order customers that had received their slide a USPS pre-paid return shipping label and asked them to include their slide internal parts. The refurbished slides started shipping on November 25.

 

[wickedbeernut]

This is the first time Jeremy has acknowledged me in over three months (refer to the Glock Elite Facebook group post below).

If you're a NPM or BMC 44X gen1 customer, have you heard anything directly (via E-mail, social media, ... any means) from Nelson Precision Manufacturing or Jeremy (or his dad, Jeff) Nelson about trading in your slide for a gen2 slide or having your gen1 slide retrofitted with a gen2 breech block? Outside of this thread, have you heard anything "official"?

It's a little unclear to me why Jeremy simply doesn't send an E-mail to his gen1 customers explaining the situation. I don't see why he needs to have the parts in order to send an E-mail.

In addition to Tim Eliopoulos, I'm aware of one person who is currently waiting (and waiting and waiting) on his 44X gen1 slide to be retrofitted with a gen2 breech block. Reportedly, the gen2 breech blocks need to be "fit" to the gen1 slides since the gen1 slides and breech blocks were drilled as a pair. Jeremy is supposedly having BoogeyMan Customs make new breech faces since he doesn't have a CNC lathe. It's unclear whether Tim's gen1 slide retrofit involved a new breech face or not. Again, you'd think a simple E-mail from Jeremy to all of his gen1 customers could explain all this.

I am a little surprised Jeremy and his dad Jeff are putting their gen2 customers ahead of their gen1 customers (many of whom have likely given up on their gen1 slide). I guess money trumps customer loyalty.

Hello guys. I have been away from the forum for a while and want to touch bases with you. I had sent my gen 1 44x Carry slide back to Jeremy a few weeks ago and got it back today with a gen 2 breech block assembly. I weighed it assembled w/o Barrel, RSA or MRD and it is 134 gr (4.58 oz. ). The Glock Slide assembled the same way is 134 gr (4.73 oz). With the OE Glock barrel, NPM RSA and my 507C the slide assembly weighs 285 gr (10.05 oz). With the Glock 44 RSA it weighs 270 (9.52 oz). The 507C is slightly less than .5 oz heavier than the RMR (IIRC).

I hope to hit the range tomorrow to test it.

From our slide weight chart, it looks like the gen2 breech block reduced the weight by 1.16 oz. Does that sound correct?

Looking forward to your range report. Hopefully it will run reliably with OEM springs.
