Took the small GLOCK 9mm, and sent a few down range. It's a little snappy was using Hornady critical duty 115 for first shots. Fed fine fired fine hits fine,,,boringly so. I did a bit of side by side with my Taurus 380(which I adore and have in pocket all day everyday). The only boggle I have is 380 is pretty blah in the defense dept, I'm sure you'll leave me alone if I start putting em in your chest BUT we'll its still light medicine. Always in back of,my mind. Heres some pics side by the glock 43 is,bigger but not alot, main thing is width. The pt738 is lost in my pocket the g43 will be noticeable. Both cover with hand for size compare, Not debating carry styles here, I do them all as needed or,appropriate BUT I pocket carry ALWAYS wether appropriate or not pants on gun in. Here's the very first 3 rounds thru the G , 7 yards 8x11 paper. Same thing for compare with the pt738, not fair as it has over 1k thru it in my hands. The g43 group will tighten up in a few,minutes practice. But both do whats required of,them. Il spend a month with new one and determine if,I switch fulltime ????
