I used to play a game and hand it unloaded to fellow cops i had the only one out of 2500, of the ultimate 250 people that took the challenge only one was able to figure how to get a live trigger before i snatched it away. I alway called it the ghetto killer because even after the embarrassment of a cop that couldn’t work it, no criminal could even fathom how to
That was an added bonus to the design feature of that pistol and similar to one of the reasons I like a manual safety on a pistol. A gangbanger used to glocks may take a few moments to figure out how to turn off the safety and that may be enough time for you to get the gun from them.
Use it. Its onky pitfall was 9mm the worlds most ueseless roound of all time, 38 super is the ultimate mix of match accuracy and when properly hot loaded hits like a 357. Or the most expensive amd unavailable 308 the 7.62 AR
Just as a note, there was some of the P7 pistols made in more potent .40 S&W but they command a huge price premium.
As to your comment about 9mm I would have to disagree on that.
The original European spec 9mm was and still is a pretty capable cartridge.
There is a fair difference between that and the much lighter, much softer shooting American target ammo that so many people think of when they think about 9mm.
In addition, in the USA due to lots of cheap guns being made like crap, ammo manufacturers for many years, tended to play things a lot more carefully so nobody sued them when their hunk of junk blew up. As compared to in Europe where anybody legally shooting a pistol would have to be one that went through the CIP Proof verification that it was capable of handing about 50% higher than normal full pressure loads without blowing up.
.38 super really isn't even in the running, it has a cult following (especially Mexican heritage folks here), but outside of competition in 1911 / 2011 or CZ75 type frames and revolvers, it's pretty much a very niche caliber.
Generally handguns are a compromise and 9mm has pretty much won the market for military / law enforcement / civilian SD carry because is is the best all round compromise, especially with modern pressures and bullet design.
If you think 9mm is a useless round, get some of the Underwood Extreme Penetrator ammunition and see what it can do.
(Don't feed your P7 a steady diet of it. I probably wouldn't risk shooting it out of the P7 at all. Something like a USP 9mm full size or a full sized P30 can handle limited quantities of it.)
In the USA lots of things were tried by both LE and Civilians searching for the "perfect" semi-auto SD round.
In revolvers, .38 special was eventually superseded by .357 magnum as the perfectly balanced SD round.
In the Semi-auto world, many things were done to try to compensate for the deficiencies of American 9mm ammo at the time, once people wanted to move away from the larger, low capacity, heavier .45 auto pistols.
10mm was the ultimate penetration and win the fight round, but proved to be too much for a large segment of the population to handle, and in addition at the time it was hard to produce pistols that could stand up to a heavy diet of full house rounds.
.40 S&W and the niche, penetration optimized .357 Sig had quite a lot of success, but eventually modern 9mm rounds got good enough and metallurgy and gun design improved so that the cost, recoil and capacity differences (cost being a huge part as was recoil) of .40 S&W didn't make as much sense as the 9mm for a lot of people.
In Semi-Auto, without going to something crazy like special designs and frames for .357 magnum, .44 magnum, .45 auto mag, .50 AE;
You get the niche .45 super and .460 Rowland at the top then go down to 10mm, then to the .40 S&W / .357 Sig, then from there go down to the 9mm, then to the .380 (which is a rather lackluster round).
Accuracy is largely dependent on the guns.
.38 Super is rarely seen in the wild outside of target designed 1911 pistols, which are also capable of being tuned to be very accurate with .40 S&W or 9mm.
