Max,
Up until a few years ago, all I would look at were revolvers (S&W or Colt) and 1911s. That changed after I worked/shot my first GSSF match, then shot my 439 in the first Adaptive Defensive Shooting Summit. The 439 hurt my time plus scores with the first shot DA. Fortunately, that is where I won my P320 X-compact. After borrowing a Glock for my first and second GSSF matches, I decided I needed my own.
Fast forward. I have since won my Sig P320 X-compact and a P365, plus a Glock 30, and when I shoot GSSF matches, I'll be shooting 5 divisions this year. Because I had similar apprehensions, I selected a P365 with manual safety, which is my carry arm when I can legally carry. I am starting to warm up to the Glocks, and looking at pocket carrying my G42, and possibly IWB my G26. However, when I would want to reholster any Glock, I would first remove the holster, reholster a hot pistol, then return the holster to my belt. I am fond of the Blue Star kydex holster.
The only time that I reholster a striker fired pistol is during matches without removing my holster is when I have shown the pistol to be clear.
Just a suggestion on a good deal. If your good deal is more than $425 plus tax and NICS check, you might want to consider joining the GSSF. It's $35 for the first year, but you can purchase a Blue Label Glock 26 Gen 5 for $425 plus tax and NICS, plus be eligible to enter GSSF matches, which can help to build both your proficiency and confidence in a striker fired pistol. Also, if the standard 5.5 pound trigger is too light for you, you can add either a + connector to increase the pull weight, or get a New York trigger.
If you practice safety, it will become second nature!
