It takes less than 2 lbs of pressure to hold the squeeze cocker in place after the initial squeeze. Sqeeze hard, then relax to your normal grip and it will not decock. Keeping a lot of pressure on the squeeze cocker is detrimental to good shooting.
The heat issue is frequently mentioned, but is only of significance if you are shooting a lot of rounds at the range. In a self defense situation, the gun will not heat up quickly enough to ever be a problem, even if you are fending off a gang.
As for the price, I dont think they are over priced a bit. In fact, they are a bargain. I have seen new ones going for $1200, and I bought a LNIB for $900 six months ago.
I own my share of custom 1911s, and have way more in some of them than $1200, but the P7 is as accurate and reliable as any of them.
What I cant figure out is why all guns cant be P7s?
