Anyone here useing this part?
I just installed it into mine, gonna do some testing hopefully tomorrow. Would like to hear from those of you who have experiance either good or bad. |

I will attempt to explain .
When I first read about this, I was very doubtful. But, after having it explained to me, and now having seen/installed the part myself, and reading reviews till Im convinced enough, I believe it to be an improvement to the pistol, HAVING NOT YET TESTED IT MYSELF. I was going today, but Im down with some back issues, sitting here stove up, so no range time today. Anyway, this part is laser cut, precision machined, slightly extended on the sides for easier takedown. BTW...I LOVE this feature. The extension, coupled with the much more "grippy-er" laser cut sides, make takedown significantly easier. The part is perfectly flat, straight, and the barrel locking groove narrower than stock, resulting in a tighter lock-up, with no affect on reliabillity. Mr. Graham gaurantees a 7%-35% increase in accuracy or your money back. After looking at the stock part,which my pistol has many thousands of rounds thru it, a Gen 3 G21 bought in 2005, it is worn unevenly on one side. This part locks up more solidly. The gent who makes this is in Texas, well known around the Dallas gunshow circuit, and his name is T.R. Graham..aka The Glocksmith. $33 shipped to my door, Ill try it out,and see what happens. BTW..he recommends 200 rounds thru the gun before checking for accuracy. |

Improvement in accuracy from a slide lock?  Yea, can anyone explain that? |

T.R. Graham is a great guy, and I learned much of what I know about Glock pistols from him. The theory behind the part seems to be: 1. Laser cut, hardened rather than stamped so the part is true and less prone to flex. 2. Tighter cut on the barrel locking portion, which makes the barrel's lockup more consistent. 3. Slightly extended and perhaps a tiny bit thicker as well I'm tempted as hell to buy one, but I'm going to be putting my G30 up for sale here soon and have no real need for it on my range toy 17C. Well, not yet anyway... Anything Mr. Graham makes and guarantees is top shelf in my book though. |

Ahh I see, I was under the impression we were talking about the slide lock/release lever as well...disregard.
I wasn't really aware the takedown lever had much to do with accuracy either though...interesting theory I suppose, I'm skeptical, 7-35% is quite a wide range of improvement to claim, and would be tough to prove without some serious benchrest shooting. I'm not saying it isn't possible, just never heard tell of it. |

I'm not saying it isn't possible, just never heard tell of it. In theory I can see how that part can make a difference, however every glock I have owned or fired has been more than mechanically accurate enough, certainly more than I can take advantage of. But if you are one of the top percentage of shooters that can benefit from squeezing out a little more accuracy, it might be worth a try. |
| I'd like to see a blind test of this thing. Don't let the shooter know which pistol has it installed and see what happens. I'm not doubting this product at all, just wondering if there is a placebo effect going (for some) on here. I did read the thread on glock talk and it is interesting and makes sense. |
Consider why you need to pull the slide back marginally to pull down the lock. The barrel has a ridge on the locking lugs which engages in the cut on the lock. That's also why putting the lock in backwards or any other direction causes some real issues  I'd like to see some more data on it too. It seems to be a cost effective way to shrink groups in a similar manner to other barrel impingement tricks used on 1911s (via the bushing), or built into older Sigs. More consistency is always a good thing in barrel lockup. Quoted: Ahh I see, I was under the impression we were talking about the slide lock/release lever as well...disregard.

I bought one of these for my G34.
I shot it once since the install and if there was an improvement it would be at the lower 7% end which I would gladly take on this thing. It is what I expected, as the higher % of improvement is claimed to be on the 40cal. , I will have to do more testing back to back. What I did find is it is a much higher Quality part. Slightly wider side to side outside the frame and thicker front to back. Teeth are sharp lazercut which I found to grab my off hand thumb during recoil with my normal hold and could feel my thumb disturbing the lock up and down. When I got home I ground down the sharp edges and reshaped with a file to resemble the factory part. Feels better dry firing, know more later. I never saw the need for the extended slidelock on a Glock as I have no issue with take down. I have not got back to the range to retest with all the rain and still raining sideways at the moment  (pure muck now) 
I am going to shoot them back to back when I can sit down and bench the gun to get a better idea of actual improvement. |

Triggerbender-
When you shot your pistol the one time with the MGSL...did you shoot the recommended break in aomunt of 200 rounds? I myself plan on doing some extensive testing once weather/time and my back allows. Ive see/read reports of some Glocks really tightening up after the new part was installed. Again..each pistol will react differently, but hell...who wouldnt take ANY accuracy increase w/o sacrificing reliability? |
|
Seems like a no brainer upgrade now that I understand how the better quality part helps acuracy.
However, I think further testing is definately in order here. Does anybody else make a part like Graham's?? Tons of folks make just about every other custom/upgraded/improved design part for a Glock, except this one... that seems weird Subscribed

When I first installed the part you could feel a slight hesitation and "snap" when the barrel lug was centering in the slot of the MGSL if you rode the slide down slow on an empty chamber. I hand cycled it and dry fired probably 100 plus times before I went to the range. The hes/snap gone by then. Shot up 450+ rounds that day between 2 9mms. As soon as the muck drys up I plan on more testing back to back with the original SL, it's still F*****G raining , been screwing up my plans for weeks now.
Please post your findings when you get back to more testing.
