Hi Incursion;
I don't know why the quickad would say that the P7 isn't fun to shoot. I think my P7M8s are LOTS of fun to shoot, and I've owned this gun & shot it regularly for 15 years. The stiffness of the P7's recoil spring DOES make the felt recoil LESS, but still permits easy retraction of the slide by hand. It's a narrow, flat-profile gun that's easy to carry & conceal. Since it's all steel, it is a bit heavier than the Glock 19, but not noticibly so when carrying it, at least not to me. The capacity issue is easily handled, by the way, by carrying an extra magazine. Since they're flat single-stack magazines, I find it easy to carry two spares. It's actually easier to carry my P7M8 with two mags (for a total of 25 rounds of Remington Golden Saber 124gr 9mm+P) than my Glock 30 with one spare mag (a total of 21 rounds of ProLoad .45ACP 200gr+P), since the Glock and its staggered magazine are fat little critters.
I think very highly of the engineering in both guns, by the way, and I often disassemble my guns just for fun, to admire their designs. Both are well made, nigh-indestructible, reliable weapons. BUT, if you want the 9mm caliber (and I think it IS the overall-best choice in a first gun), the P7 is significantly more accurate & precise than any of the 9mm Glocks.
You asked about weights. According to H&K's recently-published history (H&K Historie 2000, nur auf Deutsch), the P7M8 magazine weighs 70g empty (leer) & 165g full (voll), or about 2.5oz & 5.8oz, respectively. Best.
