Wishing you safe “handling” in your journey.
FMJ - full metal jacket, many are more rounded nose, some claim feeds through and cycles more smoothly, but may over penetrate if a higher caliber.
JHP - jacket hollow points, hollow points, some claim they can cause a jam more easily because they are not as smooth curved shaped, though less chance of over penetrating, being aware they cause more damage to the body targeted.
1911 - Don’t own one currently, but studying them, one other characteristic I like about them are those which comes with a safety, such as manual thumb lever safety, or grip safety. Not sure if you are into loading one in the chamber or not, a very personal decision, a few other posts herein discuss it, a serious topic in terms of safety, accidents, or if one feels the need to be that much more prepared per se.
Safety at home with your firearm first, education and training first. Until you have met someone in person who’s told you their safety story, you may need to do a lot of reading or viewing safety tapes.
I’m a huge fan of safety/chamber flags. Some range stores sell them. Amazon had some yellow and red ones. I liked the yellow ones, not bought the red one yet. $1.35 for one, saves a life, limb, and/or a world of hurt. Bought a few for all those close to me - who “own”.
USCCA store has barrel blocks, which I prefer over flags, so I got some of those too, they are great. Though for calibers smaller than .380, the flags worked well, found some yellow and red ones on Amazon. I oil them for a smoother fit.
Best to you - friend.
