Greetings - I have finally put together the $$ for a 19X - but I've got (prolly a dumb) question first. Do the 19X's have the older/better finish on the barrels? I've seen a few posts with photos about the Gen5's incl G45 having a barrel finish that wears away quickly. One photo (here) showed a lot of barrel wear after only 250-rd on a G45. I hope, and assume, the 19X has the more tenacious (Tennifer ) finish... Thanks!!
