@audio1pro The slide width right at the rails is 1 inch on the P6 and the P228. The dust cover on both is .9 inch on both. It looks like the slides should be interchangeable, but I can make them go. So they are very close, but not the same. The grip frame is the big difference. One being single stack, the other being double stack.

This P6 was a police trade-in that was a little scratched up. After a few years wondering what to do about it, I had it Cerakoted with a subtle two-tone treatment and installed a SRT trigger. It still has the bar-dot sights which I find very useful. Recently I installed the Super Strut which lighted the action to about 10 lbs on the DA trigger pull. I had to relieve a spot on each grip panel to make room for the mainspring seat. This pistol fit my had as well has any gun I've fired with the possible exception of a Browning Hi Power. This is my traveling gun if I go the to left coast as it doesn't exceed their magazine restrictions.
