I have had my P11 for over a year now and have put over 1200 rounds thru it...ejector went after 600 rounds or so...cheap fix...didn't even know it broke till I got it home to clean...other than that it has been 100% reliable. I purchased a few extra slide stops and mag catches but haven't needed it yet...it has been reliable, is easily concealed and its weight to capacity ratio is still one of the best out there...and it's cheap!
absolutely one of the best out there. Lots of firepower in a very compact, reliable, and well built package. get yourself the metal mag catch when you get around to it. its a weak point in all the keltec pistols that use plastic. hammer fired with double strike capability..... parts availability.....durable (the p40 uses most of the same parts).......thin and streamlined......lots of versatility.....small enough for almost any type of carry yet large enough to handle comfortably....solid self defense cartridge.......keltec pistol ever made without question IMO.
I honestly dont know why people choose the PF9 over the p11. The p11 is time tested and better built. Kelgren basically took the grendel and eliminated all its faults and chambered it in a locked breach 9mm slightly bigger than a walther PPK with a lot more firepower. PPK kills it on the accuracy though.
I also dont understand how they are not more popular. Out of all the clone the p11 is still the best (even though some are pretty decent). Out of almost all the subcompact 9mms the p11 is much more inexpensive and built better in most cases.
I have a few complaints about the p11 but they are fairly minor. I have always thought they should release a gen 2 with very subtle changes IE metal mag catch, different shaped trigger with an over-travel stop, dovetail sight cut compatible with a more typical and available platform (glock, sig, whatever), slightly different cut frame to work with wider shouldered magazines. it would not take much work and it would make these guns more marketable.
As it stands its one of the most copied designs of the last 20 years. The list is long. many manufacturers have borrowed from kelgren.
P11 is one of those best kept secret guns that flies under the radar while we are bombarded with a lot of fads and crap designs that get thrown around the market, last a couple years, fail in the market, and dumped into pistol purgatory. another long list right there!
