Congrats on the new .45 ! I just got done polishing the barrel on mine ten minutes ago.The 36,either you love it or you hate it,I just happen to love mine. Not a big fan of lasers,all things with batteries fail. Get used to both,the sites and the laser,you never know.I prefer the nite sites.
Holsters,get a good leather one.
Field stripping,I don't know of any hand-gun easier than a Glock.
1-Drop the magazine
2-rack the slide (locked back)
3-Look into the chamber to see that there is no round in the gun.
Be absolutely sure there are no rounds in the weapon !!!!!!!!!!!!!!!!!!!!!!
4-Release the slide.
5-Point the gun in a safe direction "the ground" !
6-Pull the trigger.
7-Pull the slide back 1/8 of an inch while pushing down on slide lock tabs
and pull slide off.
It is very easy and all in the manual.
Good luck and be safe and a big welcome to the forum!
