All this talk about 10mm prompted me to dust off my little used G29. I haven't shot it in a good number of years; so long that I really had forgotten what it feels like to shoot 10mm.
Rounds fired were from stock I bought a good 8 years ago or so. Hornady 180 gr. XTP and Winchester 175 gr Silvertip.
Both breathed some fire from the 3.77" KKM barrel, but the Winchester really kicked up the potency after firing the XTPs. The box advertised velocity on the 180 gr XPT I have is 1180 fps. If that's accurate, then I'd say it felt like the Silvertip was over 1200, perhaps 1220 fps as a rough guess. A relatively potent round that lets you (and nearby range shooters) know that 10mm is being fired. I can imagine that the Underwood loads really demand your attention!
I find the Talon rubber grip wrap really improves the feel of the gun, increases the grip hold, and seems to even give a hint of cushioning in spite of being so thin. After putting them on all my carry guns, the hard plastic of the stock Glock grip really feels lacking.
Personally (living near a major metro area and not having any large four legged threats to contend with) I don't see 10mm being a good fit for every day carry - for me.
I'm not convinced that the performance as a defense caliber is commensurately better given the increase in recoil and longer return to target time. For me, doing a quick mozambique or just a fast double tap with great consistency in accuracy is not at all easy to do with loads like 180 gr XTP and, especially the older 175 gr Silvertip - and that's not even venturing into full-house 10mm land.
I definitely see how those who live near major four-legged dangers, or want to hunt with a pistol, would choose 10mm as an EDC, though. If I were to venture into woods where potential 4-legged threats might be encountered, I would carry my G29 for sure.
It does seem that it would be a good suburban carry caliber if carrying a bit softer load. But then, it probably makes more sense to go with a good .40S&W loading, of which there are many that are very good and also relatively soft shooting.
