I'm interested in buying a new P7M8.

Given it's a 9mm, I feel +Ps are needed to make it a truly serious carry gun. Can the P7 handle +P, or will hot loads crack its frame etc.?

ALso, why don't HK put their HE finish on the gun? I am concerned about carrying it IWB and rusting it.

DO after market finishes work well on the P7 (don't cause reliability problems?)

THanks

+P, +P+, NATO and higher are no problem for the P7 design.

The P7 is amply strong for these hot 9mm's in the mid 1980's Jeff Cooper used a P7 to develop the 9mm Super, they finally dropped the pressures down when the brass began to shred itself against the HKs chamber.

The HE finish is a design specifically for the USP, the USP and the P7 do not share the same materials but it would be fine on the P7.

The P7 is a prime candidate for almost any high quality finish, I am partial to nickel and black T on the P7.

There are examples out there of factory Phosphate finished P7M8's, which is more durable then straight blue/black finish. Most of these were Park Police left-overs (unsold/unissued).

Also, many other P7 owners who lament the durability (lack of) of the factory blue/black finish get their pistols hard-chromed, or some other finish (Black-T, Birdsong, NP3, Robar) if they don't like the chrome. Most are not as durable as the chrome, though.

A good source of info from other users is the P7Cult board at http://www.parkcitiestactical.com .

Go to discussion boards, then to P7 Cult. So far this has been the best source of info from other users and a few 'smiths I've found. Use the search function regarding finishes to get more answers to your question.

I know the p7's are made froma steel with a very high carbon content...this may be the reason they are not offered in a HE style coating...I've heard from people trying to mill the slide on a P7 saying it was tough as hell to do. the high carbon content probably has something to do with it rusting easily if not properly cared for.

P7M8, very hot load, no problem.
P7M13, very hot load, BIG PROBLEM.
The M13's I am familar with have an unsupported case mouth, shooting very hot loads will cause the brass to stick in the chamber. Such brass has to be pounded out with a cleaning rod and mallet. If the brass is weak, it can blow out the unsupported area. The M8's I am familar with do not have this problem
