I am a gIock fan. I have the G21 and G27 both are gen4. I shoot good with both. However I like the HK 45 DA/SA, but because of price and and magazine capacity, I will stay with GLOCK. I think I like the DA/SA of the HK 45. I shoot very well with the HK 45. I think I found the answer the new FNX 45 will be 15+1, is DA/SA and will be around $700. I do not know much about FN's at all. I would greatly appreciate any help with this!!!! I am thinking of buying the new FNX 45. I have not heard much about FN.
