Honestly I think Ian is really advocating for swords, axes, seaxs, & spears for home defense.
No blow through, no over penetration, & no running out of ammo!
Over-penetration in that case would mean cutting clean through your assailant, and lodging the blade into the wall or floor at the end of the cut.
Their engineers put so much time into quality & listening to their customers. Most egrnomical gun design I have ever held in my hand. Love the light weight polymer frame of the SIG Pro-series for personal weapons & love the black steel full-size of the 229's w/ all the trimming. My 229R has Tri-jicon night-sights, Picanntany rail, w/ an internal laser bore that can switch between red & green targeting. Very dependable firearms for handguns.
Yeah, I knew yours had the rail because of the "R" in the model number.
If I want to put a laser on mine, I'd have to go with one of the alternatives, such as laser-grips, or a laser built into the spring guide (my dad got one of the latter, and it seems to work well enough). I don't think the "R" variants existed yet when I bought my .40 229.
Personally, I really didn't like the Sig Pro line at all. It just didn't feel right to me. The new Sig modular pistol (P250 I think?) is the first polymer handgun of theirs that felt better to me. Previously, I felt that if I were to get a plastic gun, it would probably be a H&K. Glocks don't feel good to me either. This is all from a subjective "fits my hand, feels like a weapon and not a toy" sort of standpoint for me.
I really like my steel frames. Just a personal preference, of course.
