first off, i wanted to say hello, and that ive read ALOT of useful information from this MB and i thank you all for that. ive owned a Glock 30 and 23 in the past, as well as a beretta 92 compact L, SIG P239, SIG Pro2340, and a Taurus .357 revolver. this Glock 32 is my first .357SIG gun. i bought it 2 days ago and immediately went to my local indoor range. i must say, it is a FUN gun to shoot. i think it has the sharpest recoil of any autoloader ive ever shot, and you gotta love the fireworks. its DEAD accurate and i shoot it better than i did any of my .40S&W, .45ACP, or 9x19 guns ive owned. theres really only one thing about the gun that im a little worried about, and thats over-penetration. i talked to 3 people at the store i bought the Glock 32 from, and they all ranted and raved about the .357SIG, saying it has just as much stopping power as a .40S&W, its more accurate than a .40S&W, has higher velocity, flat shooting, etc. however, after i was done shooting at the indoor range, i asked the guy that worked there for his personal opinion of the .357SIG caliber, and he agreed with what the other guys at the other store said, except that he would never own one for personal defense. i asked him why, he said because it has "horrible" over-penetration. he seems like a pretty knowledgable person, and the other guys never brought up an over-penetration issue. what do you guys think about over-penetration with the .357SIG caliber?
