The officers models are very nice carry guns.
I highly recommend the kings 306a kit for any officers model. They had a problem, at one time, with the plug breaking and the guide rod and spring flying down range. This kid uses the reverse plug and eliminates that. It also has the clip capture guide rod that makes it easy to break down. It DOES take a little modification to the slide, but it's easy:

I also highly recommend the ismi flat wound spring. It's supposedly rated for about 20,000 round where the normal officers springs are rated for just a few thousand. The only thing is it requires a 1/4" guide rod (like the kings) or it won't work. They have their own kit (which may be the kings, I don't know) but I like the kings as I like their bushing for the officers:

Just tossing this all out there for info.
