Update
Ok... Here is an update. As much as I enjoy my SR1911, I still felt the calling of the P series 45 pistol. Since the P series line is now gone, I felt this was the time to grab up one, or all 3 of the P 45s. I lucked into a mint KP97DC first, with all accessories, as it came new with. This pistol was 10 miles from my home, and made for an easy sale. The price was excellent, and I can tell this pistol was fired very little in its lifetime. I have shot it and its very accurate, and has mild recoil. I added a Pachmayr slip on grip with finger grooves because the early Zytel frames are somewhat slick. Im very happy with the P97.
I kept reading about how the P90 was such a great gun, maybe, possibly, the best 45 Service pistol ever made. I like the Decock versions of these pistols, as my long ago sold P89, was a Decock model. Since the P97 is only available as a Decock, or DAO pistol, and mine is a Decock, I wanted my P90 to be a Decock also. I lucked into a KP90DC with all accessories, from the original owner, and he claims he only put 20 rounds through it, in its lifetime. 2 original 7 round magazines with the warning stickers still attached completed the package. I have since added the Houge finger groove grips. I have not shot this pistol yet, but will soon take it to the range.
I am now torn as to whether or not to search out a P345. I will probably keep my eyes open for one, as I am curious how the 345 stacks up against the other two, but for now, I am very happy with the pair I have.
