I carried a alloy frame commander since '90 and 4 years earlier with a officers acp but never had any interest in another brand or model of 45 for as a concealed carry handgun . I'm very close to 70 now and I retired my lw commander a few months back .
I've have also kept a 40sw since ether late '90 or early '91 as a carry option, work gun or just a smaller as cc option . Back then the quality of factory 40sw ammo was lacking compared to current 40sw ammo choices but hand loaders managed to cover those short comings till some ammo producers started to catch up with better options than what the fbi wanted and then years later underwood and BB managed to produce 40sw ammo with energy levels even the 45+P can excede.
I never had any interest on other 45 pistols except for one that was bought as a foul weather or fishing trip carry as my last commander was a polished blued model .
That other 45 handgun is a Kahr CT45 that is also 45 super capable . Its a thin pistol and has a lighter weight with a very smooth under 5lb trigger pull that is more like a constant pull weight Stricker fired trigger , MIne has settled in at 4lb 10 oz average pull weight.
I knew the mid size kahr 45 like a cw45 will run with 1911 officers mags , just click it in place and shoot ! So since I have a pile of wilson colt 1911 full size mags I bought the Kahr CT45 kahr and cut a small notch out of the bottom front of the grip so the 7 , 8 and 10 round 1911 mags lock in a run reliably while the 7 round metal bottom mags fit flush for a shorter carry height if that matters . Physical size wise the kahr CT45 is far smaller than a m&p 4" compact even though both use a 4" barrel . Advertised weight in most places is off for the ct45 kahr - Mine weighs in at 24oz with a empty wilson 8 round mag .
I have harvested a couple deer with my M&P 40 that showed up under my tree stand . underwood 155gr gd hp fired basically straight down dropped one deer where it stood and the next time I used my 40sw the deer ran about 60 feet stopped looked back and fell to the ground . Both bullets passed were pass thru shots of about 16 to 17" of tissue but caused major heart and lung damage with onlythe sternum as for any bone hit . That underwood load manages 1328fps in my 4.25 M&P with a 155gr gold dot bullet and just short of 600ftlbs of energy . Today the bullet used is a xtp .
Just an option for a 45 carrier if size and weight is a concern . I now carry ether my early full size m&p 4.25 40sw or a 2.0 5" pc ported 40sw . Do I miss my lw commander ,, sure but not enough to CC it any more when I have quicker split times and better defensive accuracy with my 40sw than with my 45 .
