It's about time I picked up another Glock, this will be my third as I have a 17 and a 27. :supergrin: Looking for a large cal., more for the woods as well as HD/range. Maybe some hunting after adding a longer barrel. I think 10mm is the way to go here.
I started toying with the 10mm cartridge and am really liking it. Got to plink my buddy's Delta not long ago and I was blown away by it's accuracy and power downrange. Anyway, I'm a 1911 guy, most of my guns are 1911s so I am rather familiar with the .45 ACP cartridge. So, in a way I do want something new and different.
I will primarily be shooting 10mm, my understanding is that I can buy a G21sf and drop in a 10mm conversion barrel. I see KKM makes a barrel for this application. My question is reliability. How reliable are those "drop in" conversion barrels? Would you trust these barrels for HD?
If I'm going to be shooting .45, I'll more than likely be using one of my 1911s. The 20 is $50 cheaper than the 21 in my neck of the woods (can't find a 20sf RTF2 though).
I saw pics of a 21sf RTF2, did they start making 20sfs with the RT2 frame yet? Not sure what way to go...20 or 21. :dunno:
I have a G21SF with a 6" Lone Wolf slide and a 10mm conversion barrel.
I would not recommend this setup (yet) for a defensive gun, as it has not run 100% like my stock Glocks have. I have only put a couple of hundred rounds of 10mm through it at this point, and I'm working on developing some of my reloads with it. The chamber on the KKM is much tighter than a stock barrel which leads to possible misfeeds, especially when it's not cleaned.
I have also read trouble people have had with the conversion barrels failing to extract. I have rarely had problems with extraction, mine has only been the rounds hanging up while feeding into the chamber. Even then, it might only be once or twice in 100 rounds, but that's still too much for a Glock!
That said, the 10mm is absolutely a kickass cartridge!
That is a beautiful looking pistol you have there, I was planning on getting a 6" barrel for it, and now I'm going to have a look at the LWD slides.
For the reasons you mentioned above, I'm most certainly taking the G20 path. Like I said earlier, if I want to shoot .45, I'll grab one of my many 1911s. Thanks for posting that pic and thanks to all those who contributed here. You guys rock! Oh, and if someone can tell me when a G20sf RTF2 is due out, I'd really appreciate it. THANKS!!
DT is one of 5 different brands I've shot and checked, and I've used the same chrono to check other calibers too - it seems to be working fine. And DT clearly states velocities from a G20, with no mention of barrel length, so I assume it's the stock barrel. My results have shown that you have to use the 6" (Glock brand) hunting barrel just to get DT ammo to go 100 to 200 FPS slower than they advertise. With the stock barrel, the velocities are even worse than that, so I don't think I'm tainting the results with improper barrel length.
I have done the exact same testing of DT 10mm and 45 ammo and experienced the same results as Brian Lee. With a 6" barrel I do not get the claimed velocities of the 4.6" barrel. I like the DT ammo BUT all of mine is at least 100fps under advertised velocities. I have brought this to their attention and have gotten no reply! The Reed ammo tested seems to be right on.
Good question,I bought a 21sf and then wanted more bang for the buck,bought the 20 and was very impressed and it's just so different than a 45acp round. The 10mm is to much fun(more expensive) but worth it. If i had to keep one it would be the 10mm....nasty! Love it! So much I bought a 29......even more fun in a smaller package.....it's a disease.......good luck.
