I carried my TP9 for about two years. I liked how flat it was, the slightly greater capacity than many other small nines, the longer sight radius and full length grip. I improved the trigger, including lightening.
I was always concerned about the limited capacity and the narrowness of the grip, making it a little harder to shoot well. I now carry a Beretta Storm PX4C full size with a very similar trigger.
I have two family members who recently got CCW permits and asked for advice on a carry gun. Both newbies are interested in easy carry and simplicity, which means Kahr.
However, there has been a huge amount of buzz about the S&W M&P Shield and especially it's short reset trigger. A few weeks ago I bought one to wring out in anticipation of letting family members try it as an option.
In short, it sucked. Crudely made, requiring as much fluffing and buffing as a Keltec. It is reliable and ergonomic, but I intensely dislike cheaply made guns. Worse, however, was how badly I was misled about the trigger.
My unit must have been unusually bad compared to what many others claim, or they are trigger idiots. It had a long gritty take up, a horrendous hitch at the beginning of the striker block contact, and a hard 7.5-8+ lb variable trigger pull that just didn't want to break, and then had over travel. Because of this lousy trigger, accuracy was really compromised.
I polished everything and smoothed it up a little, but the hitch was still there and the break was still heavy. I eliminated the overtravel with some epoxy in the trigger guard. I coughed up an additional $200 to get a sight pusher to remove the ridiculously tight rear sight for disassembly and an Apex trigger kit.
With the work done the trigger is now much better, breaking consistently at about 5.5 lbs. with no over travel. It still has a slight hitch as the trigger bar pushes up the striker block, and the break is not "like glass". It does have a short reset which makes it fairly fast to shoot, but accuracy still suffers.
Bottom line: I ended up paying as much or more than a Kahr costs, got a rough gun with a poorly designed striker firing system that required additional expense and time, and the trigger is nowhere near as good as my three Kahrs have been. I won't be recommending a Shield over a Kahr.
