The standard BASIC cleaning procedure of the HK P7 is extremely simple (as described in an earlier post. The part that always makes folks nervous, (gas tube/piston) does NOT require constant cleaning, but should be done after shooting a couple of hundred rounds..
IF you don't clean your P7 often enough it will advise you of it's need as the slide will quit operating properly.. That generally never happens unless you are dedicated to seeing how many rounds you can shoot through it before it gums up to where it won't function perfectly.
I keep hearing about how quickly P7's heat up as if that were a concern for daily personal defense carry.
In my experience the HK P7 WILL heat up quickly, but quickly is relative to what you have previous experience with. Some firearms never seem to have a heat problem and if that is a big deal to you, don't buy a P7.
But my P7's (I have three) are all pretty constant in that it takes shooting 4-5 magazines, rapidly, through the pistol before heat becomes a problem..
When I carry my P7 for personal protection I generally don't even have a spare mag along.. The HK P7 does NOT heat up in the use of one or two rapidly fired magazines so that's a non-starter as a problem for me, and I would suggest most folks who chose to carry the fine HK P7 for personal protection won't have more than one spare mag along.
If you are the type person who would be put off by this, buy something else.
Truthfully, there are many new pistols and revolvers out there on the market which offer easier maintenance, more capacity, certainly lighter... And for most folks one of those is a better choice for daily carry.
But if you can be satisfied with 8+1 capacity and the weight of an all steel pistol (steel is heavier than plastic, duh?) you will find the HK P7 of absolute top quality, as accurate as any pistol I've personally ever owned or fired, and a pistol that is as reliable as anything man made can be. Being a "squeezecocker" makes the HK P7 extremely safe also.
HK P7's are like Jag XKE's... They are a bit rare, a bit expensive, and could be considered slightly high maintenance when compared to the Glocks and other plastic pistols available.. But they ARE HK P7's, and have a mystique of their very own that calls out to dedicated pistol lovers in a way that in unexplainable, but definite.
Frankly HK P7's are NOT for everyone. But I would suggest IF you have the chance to hold and fire one you will either love it or hate it... If you love it, you'll ignore the warts, if you hate it you won't one anyway.
Now, having defended the HK P7 I will admit that I chose NOT to carry one of my daily.. I just stick my puny little Seecamp LWS380 in my back pocket and I'm good to go.
So, I don't carry my P7 daily, but I'm not selling them either..
I think everyone who is a gun nut (as I am) needs a P7, BHP, and Walther P1 (or P5) in the gun case just because they are all unique to some degree, and have a great history.)
Just personal opinion, no offense to those with contrary opinions.
Best Wishes,
