I have got the Glock 20 since my earlier post. I have really come to like the 10mm so far, the Glock I'm still deciding on. I had a thread on my G20 and the issues I had with hardcast ammo. It is yet to fail with over 350 rounds of 180gr JHP but has yet to make it through a mag with hardcast ammo from Underwood or Buffalo Bore. The G20 is at my gunsmith's now getting diagnosed. The aftermarket KKM barrel and 22lb recoil spring didn't fix it.
While it's gone I traded my Sig Scorpion 45 for a Sig Tacops 10mm. I really like the new Sig 1911 10mm. It is shooting amazing with the 180gr JHP ammo. I have not tried hardcast ammo yet. I just got a box of Underwood 200gr hardcast and a box of their 140gr Extreme Penetrator ammo to try in it. Double Tap called today also and said that the 200 and 230gr hardcast ammo I had on order from them would ship today. I ordered it for the Glock but the Sig will get first shot at feeding it now. The Sig is about 10oz heavier than the Glock with both fully loaded, and the Sig holds less rounds. The Sig is definitely more accurate in my hands though, I'm shooting it as well as I have any handgun I've owned.
For an all around gun that I'd conceal and woods carry it would be tough for me to decide. I'm glad I don't have to.
I'd maybe pick my 3" S&W model 60 in 357. It shoots 38 FMJ's well enough for small game and can shoot some hotter hardcast loads for woods defense. I wouldn't go to overboard to keep muzzle jump down, but would want a hardcast bullet with at least 400lbs of energy at short barrel speeds. If I was more of a striker fired trigger fan I'd maybe go with a Glock 29. In a small, light gun I shoot that revolver better than I do any of my semi-autos. My Sig 938 would be second ahead of the small striker fired 9mm or 380's I have.
I personally want a different combination of bore diameter and energy than the 9mm, 40 S&W, or 45 offer for a woods gun. As the bore diameter gets larger I want to have more powder behind that bullet to ensure penetration. That's why the 357 or 10mm are about as light as I personally want to go. I'm no expert and have shot or shot at 0 bears. Biggest critter I've had to shut down as it charged me with a handgun was a badger, so take my advice for what it's worth. I did a lot of looking at different handgun cartridges and ammo choices and came up with my criteria on what I want, not necessarily what is right for you. Accuracy is still king and 9mm is cheap to practice with a lot.
