Hi Mas, I have a Gen2 G22 I keep loaded with 155gr GD for home defense, and my CCW's are a Gen2 G19 loaded with 127gr +p+ and G26 loaded with GD 124gr +p. I like to appendix carry, and I find it easier to conceal the subcompact without printing here in south FL. I tried the Gen4 G23 at the range and I liked it; they didn't have a Gen4 G27 yet. I have been thinking about trying a G27 for CCW. I just wanted to get your opinion on whether you think the 40 would really be more effective and what load would you recommend?
