It's funny you say that. I got my 229 specifically since we were issued M11s and I wasn't very good with it (or hand guns in general, as I would learn). I put a SRT in it, as well. I got so comfortable with that 229 and was even complemented by one of the "old-timers" at a competition about my double-action trigger pull. After a couple of years and some competitions later, I decided to grab a MK25 (with a SRT). Great gun but...
That's also when I started shooting my Glock, A LOT. And now I'm both a Glock and red dot cripple. The last time I took out my MK25, I was disappointed with my performance. It doesn't help when it's getting much harder to see that front sight now. Sadly I don't think there's a way you can put a red dot on a P226, at least not easily.
You can get the slide milled if it’s really important.
FWIW, I did something similar after shooting the M11 for predeployment qual in 2010. Qualified, but shot worse than I’d have liked because of DA/SA. Paradoxically, I liked the gun. So I bought the Mk-25 and set about getting good with it. Went from being made fun of in class (by instructor Larry Vickers, no less… it’s a strangely small world sometimes), to being complimented at local USPSA matches.
Now I have a Stealth Arms Platypus, which probably has
@ChuckMK23 reaching for his nitro pills (it’s a double-stack 9mm 1911 that takes Glock mags), but damn, I love that pistol and it’s quick, especially with a red dot. Have to train with both actions now, to stay proficient with the DA/SA. Oh, darn… more range time.
