I've had my Glock 17 for over 30 years. Never a problem and is very comfortable in the hand.I carry an M&P40c
Personally never been a fan of the Glock block ergonomics.
Great platform, undeniably reliable, but not for me.....I prefer the M&P
Technically, the M&P is the GenIII Smith & Wesson glock copy that has evolved.
Glocks........look the same as 35 years ago, but internals have gotten better.
However, I seriously would consider the XDm 5.25" 9mm that is newer.
If I had a choice, I'd take this as the #1 choice between those. Consider the Walther PPQ 5" M2 also.
The gun is surplus, aka new in box. It's probably a 2011ish made gun that is outdated. Those early models were known for bad triggers and inaccurate barrels. I read it on the innerwebz, it must be true....That's the perfect gun to buy. You know 99% of LEO DON'T go to the range like they should so that gun realistically has 500 rnds at most through it and is inspected annually. It rides around in the holster all day. Buy it.
