So I just impluse bought one of these at a local gun shop, came with a speed loader and a bunch of extra ammo, defensive and practice in both .38 spl and .357 mag. Looks relatively unused. Is there anything in particular I should know about this type of revolver? All my others have been steel frames. And is there a technique for clearing the spent cases from the cylinder due to the 2 5/8 in barrel length?
