TR Graham Match Grade Slide Lock (for Glock)

[tinkerer]

Are there any reports, reviews, or impressions on the Match Grade Slide Lock by TR Graham?

It seems he stopped production last year because the Slide Lock was causing chipping on barrels. He has restarted production with a newer variant; however I cannot find any information on whether this newer variant is as good/reliable as the old and what type of reliability in general to expect from this part. Is the increase in accuracy worth the reliability risk that going to an aftermarket part like this entails? Thanks.

In short, no.

Definitely not worth putting into Duty/HD guns.

And for competition guns, I don't know of anyone shooting limited or open division Glock guns with aftermarket slide locks.

I tried one of the original versions. Turned a PERFECTLY reliable 2005ish 3rd Gen G19 into a malfunction clearnace training device instantly. When the pistol shot, I did not see any appreciable increase in accuracy. Took it out, gun went back to being perfectly reliable, accuracy didn't suffer.

Interestingly, it was this "improvement" that taught me the mantra to just stick with OEM for Glock parts (less night sights, of course). At this point, the only non-stock part on any of my Glocks is a Vickers' mag release and some Vickers' baseplates on my G23 mags to make them easy to distinguish by feel from G19 mags. If I was seriously looking for a way to make my G19 more accurate, I would invest in a quality barrel, and send it off to someone competent to install.

Match grade slide lock just sounds ridiculous to me.

Thank you. Will stay clear.

Of all the part to change on a g-lock, why .......

It has been suggested here, and elsewhere, that this part will help increase accuracy in a Glock. The "concept" behind it, as I understand, is that the barrel will lock up tighter with this part. Thus the "cone" of fire will be smaller because the barrel has less slop and movement. Plenty of people seemed happy with the old version. Not much information with the new. In general I was weary of replacing a Glock OEM part, so I wanted to see if anyone here had an opinion of the part.

I'm still surprised that no one has offered an aftermarket locking block for use with standard Glock barrels.

Why not just fit a barrel? A properly fit barrel is fitted in three places on a Glock, all of which improve lockup about as good as you can make it...

TR is an awesome guy, very nice, and very knowledgeable about Glocks.

He built this part for guys that wanted to shoot bullseye competitions with Glocks. It's not a part for action shooting and certainly not designed to stake your life on, and I'm confident that he would say the same.

In his video "Making Glocks Rock" when discussing his own damn part as well as fitting barrels to Glocks, he states

"But always remember, the tighter your tolerances are in any firearm, the more chance there is that the gun will malfunction. So pick and choose carefully, especially if you're going to use the pistol as a personal defense or duty gun."

ETA: So in case I wasn't clear...leave it the hell alone. Get a qualified gunsmith to fit a barrel for you if you can actually quantify any lost accuracy.
