Buying new pistol, need advice

[Grape Ape]

I would agree that a Glock would be a good choice for your needs. Take a look at the model 30. It is a 45 with 4 inch barrel/10 shot magazine. It weighs in at 24 oz, so it would not be too bad to tote with you.
I have shot thousands of rounds through my duty issue model 22 (40 cal) with no problems. The only time I have seen this weapon misfeed is when the shooter "limp wrists", not having a firm grip on the weapon. I have seen this happen with other autos also.
