i used to be a died in the wool 45 acp guy. I ran across the 10mm round buy accident several years back and started to do as much research as one can do on the Internet. the ballistics alone are over whelming and hey "uncle Ted endorses the 10mm...LOL". any way i haven't looked back as i feel this weapon offers the best all round cartridge for SD to hunting. 15 rounds in the mag and one in the pipe with that much power is hard to pass up. Yes the rounds are still pricey and to get the best out of the round you will want to think about reloading but some manufactures are starting to come on board (buffalo bore,swampfox and now the big boys are starting.. even if they are a little watered down).
Over the years i have added various conversions AA 22lr upper, 40 s&W cheaper practice still decent SD and recently 9 mm conversion barrel. Yes LWD produces a 9 mm conversion barrel for it (even cheaper trigger time). I only needed a reduced recoil spring nothing else. It makes for the softest shooting 9's and i can still use the glock 20 mags with 18 x 9 mm rounds in it. so i have 4 different hand guns on one platform for any where for 250.00 (AA 22lr conversion) to 125 LWD barrels. There are a couple of other conversion barrels out there 357 sig and 9 x 25 dillion that can be had but i wanted to stay within cheap ammo realm.
I went with the glock as they have been producing the 10 mm platform almost from the start while other manufactures had various problems and some still do with the 10 mm. the glock frame helps to reduce the percieved felt recoil. i am still trying to retrain with the glock trigger and grip (not my favorite..at all) but i feel with practice i will find my sweet spot.
well thats my story and i am sticking to it.
