I recently got to check out a new P-11 and put 50rds. or so throught it. I have to say they`re made much better now than my old one. I was planning on doing the F&B to it but it simply doesn`t need it. I installed the belt clip for the new owner and will be adding a trigger shoe later as a matter of his personal preference and that`ll be it. My old P-11 has the full F&B done to it. It worked 100% out of the box but Keltecs are so simple they just beg to be tinkered with. While it functioned fine before it`s quite a bit smoother and somewhat more pleasant to shoot after the mods. One last thing,try a very light coat of grease to lube the frame rails and hammer interface rather than oil. I picked this tip up during the KTOG "Grease Wars" and it`s served me well. With almost 5000rds.(including many +Ps) through it mine is as tight as new and has no discernable wear at all except to the finish. Marcus
