I am having a heck of a time deciding between the following firearms and any info i can get will help.1st SIG P220 CARRY SAS, 2nd HK USP COMPACT, 3rd GLOCK 36, 4th PARA CARRY, they are all fine firearms with different frames, slides, lengths, weights, etc. Ive narrowed the field down to these 4. So any ideas? Tks.
