Mas, When I was set on buying a Glock 19, you advised I get 124gr JHP for home/self defense. I have a friend with a vast knowledge of firearms and he recommended Hornady TAP for warm weather carry. He then said he only carries Hornady Critical Defense for winter. The TAP is 124gr and Critical Defense is 115gr. While looking into the critical defense round, I read mixed opinions. What is your professional opinion and experience with the round? I bought 50 rounds of each. Would I be at any disadvantage carrying 115gr over 124gr in summer? ---- I read in a post (which I can't find), a guy said he was at a training course for pistols and the instructor said if you put your thumb on the back of the slide and the barrel into the target and pull the trigger, a "shotgun size" hole is the result. He was using a glock. Any truth to that and why would that happen? ---- Last question. Do you have any experience or knowledge with glock stocks? I'm thinking about getting one in the future and any info would be great. Here's an example, http://www.youtube.com/watch?v=ZY9alZRIF88 Thank you for your help.
