I have a g17 and i love it but im i the markit for somthing more i was thinking about a g21 but a friend of mine has a 10mm and says its a better round so now i dont know what i should get. Any advice?
Question? Did you do that conversion with a bbl only, and does it function reliably 100% of the time? I'm interested in doing a conversion on my 21, just wondering.I put a 10mm conversion barrel in my G30 and haven't shot it in 45 since. My early concerns were with ammo availability but lately 10mm has been more available than 45 and about the same price.
Well said.Silver-Bolt said:For target and woods carry I prefer my 10mm. For carry or home defense my .45 gets the nod. If over penetration is a concern the 10mm may not be the best choice. A 180-200gr bullet traveling at 1200-1500fps is going to need a serious backstop.
What barrel did you use? Was the barrel and mags the only changes you made?n2cycles said:I put a 10mm conversion barrel in my G30 and haven't shot it in 45 since. My early concerns were with ammo availability but lately 10mm has been more available than 45 and about the same price.
I'm getting 1462 ft-lbs from my 10mmsdglock23 said:I think "better" is kind of hard to quantify at times. Is the 10mm more "powerful"? Yes but the .45 shoots a bigger, heavier bullet too. I often load a 250gr hardcast in my G21 that will run 975 fps. That will drop a lot of critters. .45 ammo is easier to find and has better choices in terms of premium JHP bullets.
Then there's the .45 Super and 460 Rowland that can be shot out of a G21. I load for the .45 Super, and can produce 800 ft-lbs of energy with a 275gr bullet...and I have 14rds of it. It would say that's better than the 10mm.
Yeah that's pretty good, but a 180gr JHP at 1912 fps is a grenade. I'm sure penetration isn't that good since you're pushing it a lot faster than it's intended. I promise my 275gr will out penetrate itI'm getting 1462 ft-lbs from my 10mm
