Yea you are correct. 10 round mags for non LEO/military.
If your dead set on a g19. Order it yourself via gunbroker, buds, etc. And ship to an ffl. It may be even cheaper that way. Unless you meet the blue line for glocks.
Blue line is for government employees. Some are ffdos, fams, firefighters, i think ems too (you gotta ask that, not really sure)
I know sec hawaii has blue line for glocks and sig sauer. As well as primesports (only sig atm though.)
Personally, i like g19s. Ive had all 3, g17, g19, g26. All are gen 4s. I couldnt hit shit with a g17. No bs, idk why. It felt weird to me. I still love my g19 and g26. Trijicon hd sights. So i sold my g17 and been happier. I assume its the same grip angle on paper, but in reality it feels completely different to me. Thats just my speculation. Ive used my friends gen 3 g19 and his gen 3 g17 rtf. Same thing, i could peg the 50 yard target adequately or good enough with his g19 but the g17 i hit the berm all day long 🤪. Lol. He runs both trijicon sights too.
Since you have time like you said. Wait for 4th of july sales. I can almost guarantee youll see good deals on the web. Prob most shops too, now that everything is somewhat going back to normal. I have a feeling there will be alot of sales cause they need to move products to make up for losses. Gucci just had a sale on smaller items which is pretty nuts cause ive never seen them have a sale ever.
