View Full Version : Glock 20,10mm,conversion

02-22-2012, 8:32 AM
I have 2 Glock 21s for about 15 years now.I want a 10mm for something different.Read a few Glock forums about just dropping a 10mm barrel in my 21.Some say do it,others say no.I am past that now.I bought a 10mm ported barrel from another Calgunner and now want to buy the slide stuff to use on my 21 frame.
Question:What/who sells the slide assembly without the barrel for a reasonable cost.I have Glockmeister in mind and will sell the factory barrel out of the slide package,if that is what it takes.Please PM me if you can help.Thank you
Thanks for input about buying a new one,I know they are cheap.I have several.I am pretty poor right now and trying to go the most reasonable way to get 10mm.

Glocks are cheap... Just buy a 20/29

Lonewolf also sells their own slides. Check them out.


Also, browse the classifieds at Glocktalk.com. I see some bare slides on sale there sometimes.

Less costly route might be getting a KKM 45 to 10 conversion barrel. This is what I will do with my G21 eventually.

Drop the barrel in; change out the magazine and shoot away.

I have been waiting for over a month for my KKM G21 to 10mm conversion barrel and 10mm mags, all from Glockmeister. I have a couple hundred rounds of test loads all loaded up with no where to go. I can hardly wait, in fact, if I have to wait much longer I think I might just call and cancel the barrel and order a G29SF.

I've actually been thinking about doing the reverse (I have the G20) but more than likely will just pick up a complete G21 instead. But, there are options out there, like Lonewolf, if you're looking for a complete slide assembly.

Anyone tried the .50GI conversion kit.

I was thinking of doing the barrel conversion before with my G21.
But decided to buy a G20 instead. No more worries on anything.

Sure do, less recoil than a 45 more of a novelty really. It's just cool to say you have a glock chambered in .50
