My first handgun purchase was a glock 26. Then I sold it and bought a ruger sr9c reason being the Sr9c isn't as blocky as the glock. They both are really good guns
I carry a colt combat commander all the time including home, carry what you will carry everyday, meaning something confortable that you will carry, never leave home without it. Purchase good carry equipment, holster and belt that offers security and retention. Peace, Love, Colt 45.
Go to a range where you can rent different guns. The subjunctives matter, the trigger pull and how feels in your hand. Felt recoil and accuracy should also be considered in your choice. Those are questions only you can answer for yourself. Once you made your choice get good equipment then practice, practice, practice and practice some more. Not just range time. You don't want to find out you holster doesn't secure your firearm in a public restroom. Sadly site of many negligent discharges... learn to let it fall, most were cause by grabbing it and getting the trigger. Start with empty chamber full magazine. Wear it around you home for days before you leave the house to find where it's comfortable, concealed, and accessible. Once you think you have it. Go sit in you car and read a book with seat belt on. Better to learn it's uncomfortable when not driving. Don't forget to sit on passenger side side as well. Better to work out/around any issues early, than to leave it at home.
I carry S&W M&P45c as my EDC in Tucker Gunleather "The Answer" IWB hybrid holster, with Blackhawk Instructors belt (reinforced riggers belt) and Perry suspenders. Looking at getting a good quality leather gunbelt soon. I also use Kimber Custom Eclipse full size 1911 in winter months. I also have a Ruger LCR, but I carry it the least. Find what works for you. Welcome and stay safe.
You can carry anything that you are willing to dress around. I have carried a Glock 21 IWB in the Summer under a T-Shirt and I have carried a NAA Mini. If your back can handle a heavy gun on or in the waist with a cover garment works well. I pocket carry a back up LCR357 and main carry a SP101 or Taurus 617 / 357 IWB at the Appendix position daily.
I have a SR9C myself and it is a great carry gun. I think you would like it. I did have a Glock 19 but felt the same way as you so about it being blocky and the grip seemed to be abit large for my hand.
So Forest, now that you got replies for an assortment of firearms, it should still come down to you trying them on and walking around a gunshop or doing something that is akin to due diligence before you choose. Not sure why you begin with only the 2 firearms but you should be open to any and all as far as initial fit on you and perception of mfgr. Even caliber should be open for discussion. You want to pick the right one first--go to a larger gunshop, if possible a gunshop that carries many mfgr, caliber etal.
