Glocks are good.Glonks are good that way too. I have drop in 9x19 barrels for all my .40's sizes and... while I do have some 9mm mags.. you can run 9mm in .40mags just fine. Pretty cheap alternative to run 9 when the 40 seeds run out.
SIG DA/SA guns are better IMO/IME.
After owning/shooting striker fired guns (Glocks & Kahrs) for decades, I just never liked the striker fired guns - the trigger suck IMO. Switching to DA/SA trigger guns like the SIG 226 was an improvement for me. YMMV.
