A lot of factors come into play when choosing a sidearm.
How it points, trigger, ergonomics, features, reliability, looks and cost.
After a couple months of looking for a hi-cap .45 I settled on the FNP-45
For anyone looking to check one out, go to the FNH site and go to the dealer locater. I found a dealer that was local and he had several of the FNP lineup.
I looked at a bunch of .45's and shot a few at the range. I never shot the FN before buying it though. Once I picked it up I knew it was the one.
Myself I like DA/SA pistols. You can also get the FN with a manual safety if you prefer to carry at condition 1.
The decocker was just fine for me. DA pull isn't that bad, I haven't measured that yet but SA popped at 4.2 pounds. Good enough for me.
I wear a size 10 Mechanix glove and am using the arched backstrap on it. It seems to conceal well with a long shirt on me. I'm 6'2" and about 170 lbs.
Being a new pistol holsters are few but there are some if ya look.
Bladetech and Crossbreed have them.
I am liking this one from a local company. It comes with clips to carry it IWB or OWB
