By pressing on the back of the slide, you then hear a 'click' as it locks into battery. It dod not do this on my glock 22 and am just wondering why. Thanks.
The reason for this is that different guns have different tolerences. The slide movement and "clicking" sound you hear on your G34 and G23 is due to the MGSL wearing in and seating itself to the barrel locking lug on the barrel. (With use, a thin shiny wear line should form on the bottom edge of the barrel locking groove on the MGSL) This is normal with a new MGSL, (or with one that is swapped into different guns) and will generally disappear within the first 200 rounds fired. If this condition does not correct itself after a 200 round break in, please call me at : 832-695-7192, or email me at Grhm458@cs.com.

Is there a definate answer on the legality of this item for IDPA in SSP and USPSA in production? I am shooting in the IDPA World Championship match in a few weeks and if this part is legal I would like to use one.

Thank you TR. I will put some rounds through it and see if it is better. Thanks for the help!

Don't know, don't care. I don't think much of the People's Republic of California.

But, you are right...its I-R-V-I-N-G. In the great state of Texas. On the 10th and 11th of September.

Thanks Mr Graham! The MGSL really works! I'll be getting one for my 26 soon.

Ive got a chrome pin kit in my glock. Is this part naturally a metal color that gets painted black? If it is, are you willing to sell one unpainted?

It was laser cut and treated (chemically) to protect from rusting, as I recall what Mr. Graham said. He did that in batches.

No, sorry. The MGSL's are black oxide finished like the Glock slide and barrel for corrosion resistance.

In IDPA SSP and, as far as I know, in USPSA Production, internal modifications to "enhance accuracy" are permitted. Since the MGSL is (sort of) visible externally, and doesn't look exactly like the stock part, the situation is ambiguous. I suggest checking with the governing bodies of those sports for a definitive answer.

just installed one of the mgsl on my 19 and it is defenitely a must- have a/m part!

after an inital 100 or so rounds, the groups begun to form tighter and tighter.

can't be happier. 2 more will be installed shortly on my 26 and 34.

thank you ,mr. graham!!!!!!!!

Not saying this piece don't work, but where are you guys buying these glocks from, that have such uneven barrel lug contact? Six buddies of mine have glocks, including myself, (for 7 total) and I have been thru every one of them, and not a single one has an uneven contact patch on their slide locks... What are you guys doing to your guns?

I must live under a rock. Just saw this thread for the first time. Did not know that little piece could be the reason I was all over the target during practice last night.

I never posted back about the results with my G23 - it seems to have significantly tightened my groups, so it was worthwhile for me. The transaction with TR went as smooth as possible. Thanks TR!

Any details? What Gen G23? What kind of load? What kind of group difference? What distance? What position (rested from bench, offhand, upside down with one eye closed? - lol)?

I've been thinking about getting one of these, but I'm just looking for more specific, quantitative feedback.

One other thing - for the guys who have had these installed for awhile, have you had any evidence of chipping on the barrel lug that engages the groove in the lock? There's a picture running around out there purporting to be damage of this kind, and I'm wondering if it's actually an issue.

(Edited 1/6/12 to summarize)

I installed an MGSL in a new G26 which now has chipping on the barrel lug. The chipping is not as severe the one referenced above (search the internet for more details & photos), but my gun has less than 100 rounds on it.

I cannot state with absolutely certainty that the MGSL chipped the lug on my G26, but I believe it did. The G26 is a recent Gen3, so it's possible that the lugs are now more brittle, but I doubt that's the problem. I just now examined my other 5 Glocks (with many more rounds than the G26 & a MGSL never installed) & none have chipped lugs.

It was a 3rd gen. G23, 25 ft., offhand with two hands. 180gr. reloads. I didn't do any scientific testing. I don't have a Ransom rest.

I shoot my G23 often enough that I have a good feeling for the typical group size. After the break-in period, I'm confident that my average group size decreased enough that I'd say it's worth the cost. I really didn't have any reason to try to prove the effectiveness of the MGSL to anyone but myself.

Good info. Thanks for clarifying.

The material used to make your barrel is MUCH harder than that used to make the slide lock. I highly doubt it was the slide lock that chipped the lug. Have you ever dropped it? I would call Glock an let them know, I'm sure they will replace it. I run the mgsl in all my glock's and have never had 1 issue

Have you read this: http://www.blogger-index.com/3785529-green-amp-brass

I would think as you do, that the barrel is harder than the slide lock. I wonder if some barrels are hard to the point of being brittle and that the lug chips when encountering the narrow groove of the MGSL. As you have said according to your own experience, it's not an issue, so I wonder if Glock had some barrels that were a bit brittle.

Maybe a better question would be, has anyone experienced this kind of chipping using the stock lock?

And, I think it's important to note from the link above that the operator had replaced his recoil spring with a 13-lb assembly. Stock Glock is 17#, if I understand correctly.

I agree that the barrel is harder... but, as JLarsson says, hardened metals are also tend to be more brittle. The MGSL is not Tenifer-treated, but it is pretty hard; I just took a file to the one I have & it would not dig into the MGSL as it would into mild steel.

No, I have not dropped the gun or barrel. How in the world would it ever hit the floor, etc, in such an odd place? The chipping is on the barrel side of the ledge, so if dropped on a hard floor, that edge would never hit the floor.

Also see JLarsson's link... that barrel lug is much worse than mine.

My barrel is still functional & I do not want a mis-matched serial number even if Glock will replace it. I do not think it is fair to ask them to since I have used an aftermarket part.

Please take time to check your barrel lugs with a magnifying glass & let us know if you see no damage. The ledge that gets chipped is very small (but very important).
