I have heard reliability and durability are good. I do believe the .50gi is only slightly more powerfull than the .45acp, and the 10mm is much more powerfull than even the .50gi. I know it would have a certain "cool" factor to have a .50 cal Glock, but you would actually be taking a step backwards in stopping power, ammo availability and magazine capacity.

The .50GI expanded bullet looks like a boat propeller and is almost as big.

Yes the 50GI is a great round, GunCrafter Industries has 2 defensive loads for it 1) 185gr CHP @ 1200fps 2) 230gr CHP @ 1000fps out of a 5"bbl. Yes it is about the same power as the 45ACP, but it is a .50 caliber and both of the loads above expand to 1" in diameter....... I have the standard GI conversion and also have received a new 6" bbl that I plan to cut down and thread for a new suppressor I am having made

I have grown to love the 50GI, I have 2 Encore bbls chambered for it (don't have a pic for the newest one), a DI AR-15 and also a MAC10. (yes the AR-15 is a registered SBR)

It is a real cool conversion.....I am a GI Dealer and have the slide kit in Melonite. It has proven to be just as reliable as a G20 or G21.....Here is an older picture I have on a beater frame I had laying around. The frame has since been replaced, but the idea is the same. The picture shows the 230g CHP .50 GI next to a Barnes, Gold Dot and Ranger 230g .45.

I thought about it for my G21SF, but I would rather have the greater power of the 10mm. I think the biggest concern would be the cost of shooting it. The bullets are expensive even if you reload. It is a cool idea, and having a .50 caliber Glock is awesome, but it's just too similar in power to the .45ACP+P for me. If it were $250, I'd likely try it out, but not at $500 (I think that's the cost).

The bullets are not that expensive, I ordered the 300gr Rainier plated bullets 500 for $92, the 45 Rainier 230gr are $84. If you go with other mfg bullets the 45acp can cost more.... As for powder they use the same types and close to same charges so no big difference there and primers are the same also, so the cost per round is a few cents more for the 50GI. The big thing for the 50GI is that it is a bigger round that is very soft shooting and is accurate. Yes the 10mm has more power but the nice thing is that when you are done blasting away with the 10mm, take 30 seconds remove the 10mm slide and install the 50GI slide and have fun shooting 300gr bullets @ 750-800fps. One of the things I noticed when shooting my 10mm with anything under 200gr bullets they smack the steel targets but when hitting the same steel targets with the 50GI they are slammed down with gusto.

Those two pictures that glock2740 pulled over from 475ar10's post are very nice. What is that with the colored grips a converted Contender? I thought about converting my G21 over to 50GI but decided to convert it to 45 Super instead.

I heard that they have come out with hotter 50GI loads, is that true?

I want one , but would want a dedicated lower for it. Then figure the 550 for conversion it would put me at 900 range. So until I find a good deal on a used one I cant see it happening any time soon.

It is an Encore that I had a 5" bbl made for, also have a 15" bbl for the Encore that is a tack driver. Guncrafters has 2 loads that are for defensive use 1) 185gr CHP @ 1200fps 2) 230gr CHP @ 1000fos and both expand to over 1" in diameter.

So u CAN put the 50 gi conversion on the 10 mm? Cause guncrafter says it has to be the 45 acp, but I'd rather go with the 10.

I own both a G20 & a G21 and have toyed with the idea of buying the 50gi conversion slide. I guess the cost of the slide and the ammo has kept me from jumping on it. Then again, I just spent $750 on a Springfield RO last year that would have funded the Conversion slide, 50gi dies & a bunch of 50gi brass & bullets &/or some factory 50gi ammo. This is why I keep churning it over in my mind. My G20 eats some pretty expensive ammo, just as my 357sig guns do. Maybe one day I'll just jump into the 50gi pool head first and drop a grand on a kit & all of the supplies that one needs to be totally "in" the 50gi shooting club. Until then I'll shoot my 10mm, 357sig & 45LC ammo and wish I had just shot a 50gi conversion gun. (Heck, the 45acp ammo isn't exactly cheap these days either now that I think about it)

I also thought that either the 10mm or 45acp frame would work. I wasn't aware that it had to be the 45acp G21. If that were true it must have something to do with the ejector maybe... although that would be a simple fix.

Checked out that extractor assembly. Depressor plunger is same for 45 and 10 mil, depr plunger spring is the same on all model glocks. The only thing that needs to be changed is the extractor w/ lci, which costs eighteen bucks.

I got a 50GI for my 21 lower. It will fit the 21 and 20 lower. It shoots great. Its very accurate and is very controlable and it's a FIFTY!

Out of curiosity, has anyone done any gel testing with this caliber? I am really curious the actual performance specs. We've all seen the various examples of hyper-expanded ammo from every caliber, but when they barely penetrate 8" it isn't quite as impressive. I am curious how they actually perform, because they look almost too perfect to consistently expand like that?
