There is a PSA complete slide with a holosun ($310) and threaded barrel and suppressor sites for only $420. But then, for $679, you can get a new PDP with a free new red dot for the next month. Decisions, decisions...

 

I just bought my second PSA Dagger complete slide for $175. It came with TruGlo night sights and DLC finish. PSA calls it complete, but it does not include a barrel or recoil spring. I have barrels and recoil springs already so I saved $80 on the slide. My previous PSA slide included the barrel, recoil spring, AND a Holosun 507C X2 Red Dot and Suppressor Height iron sights. Using it on my Glock 23, it has run flawlessly.
Obviously I am very happy with it. Should receive my new one this week. PSA gets my vote, I have several AR lowers, and uppers which run great full auto with my M16 lower. They also really support our Second Amendment.

 

I've used several different aftermarket slides on my builds with no issues except for Strike Industries Lite slide, which I have on a G19. It didn't want to cycle correctly. A quick Forum search revealed that the fix was either change the recoil spring due to the lack of inertia from the lighter weight of the slide, or shoot strictly +P ammo. after a few hundred rounds of +P through it, it now works fine on anything I feed it now that the moving parts have all got to know each other well.

 

In my experience. I found LFA slides to be a very good option. Out of all the slides I’ve bought it was the only slides I’ve dropped right on with no issues and are extremely accurate. If you get a complete LFA slide with their matchgrade barrel (fluted and crowned) like a match set. It’s super smooth. Lone wolf is ok but may need a lil tweaking. PSA is good. But I just don’t like the way it looks to me. But if you like it try it out. It’s pretty quality stuff for the price.

 

I strongly advise against it unless it's a fun only plinker.i don't get this and it's really irritating aftermarket slides all over the place in quality. Just about any at upper or barrel drops in flawless yet glock slides are all over the place in critical dimensions and it makes me irate .I had a patmos brand new slide and barrel and it basically came with an out of battery issue (the barrel hood was visible over the top of the slide) it was dangerous Garbage I couldn't believe they sold something like that to consumers . I had another after market slide forget the brand but it was the opposite too right and needed to be fit to a standard glock barrel to fit and close
Glock genuine OEM is absolutely nothing like the after market junk you can find .it's almost mythical how the parts are so smooth and fit perfectly together. While it might not be pretty the incredible finish and tolerances make up for that not to mention reliability

 

Nothing extra is required for use on Gen 2, 3, or 4 frames. A Gen 5 frame requires the backplate be replaced with a Gen 5 backplate.

 

I have always been the odd duck I guess. My two most used and favorite Glocks are a 23 gen 5 and a 30 gen 3. The only thing I changed was the front sight post on the Glock 23. Everything else is 100% stock. They shoot great so I don’t touch them.

 

When i wanted to try running a dot, i bought a Brownells slide & parts for my gen3. Runs great, only a bit more than milling & i just swap bbls Back & forth.

Yes, I know a slide adapter is not required. Which is why it was phrased as, “What adapter if any” The if any part means it’s understood it’s not required. But some don’t like the gap it leaves without using one.

A Gen 5 frame will need the PSA backplate swapped out for a Gen 5 backplate.

I’ve long since known a Gen 3 back plate is not compatible with a Gen 5 frame
I either replace the Gen 3 type back plate with Gen 5. Or I alter the Gen 3 to Gen 5.

**Oh and here’s a G23.5 slide on a Gen 3 19 frame. In case you think I need any more “advice”

Another vote for the Brownell's optics-cut slides.
I have a G19.4 with one and it's been flawless. I ran 1,000 rounds through it before using it as a carry gun, with zero issues and no problems with optics mounting.

The only things I'd change about it are the top cut-out and the forward slide serrations. The cu-out hasn't offered any tangible benefits, but does trap lint, etc. I don't like forward serrations at all. They're just another abrasive surface and I was taught malfunction clearances that did NOT involve putting my hand/fingers near the muzzle of a gun.

 

I've had Zev, Agency, a single BEC, and recently picked up a LWS slide.

No issues with any of them, and the LWS appears to be a mill job on a OEM slide with some beautiful machining and finishing work.
