Had to take time and make introductions all around, let everyone meet the new girl. I had forgotten just how nice one of these things feels.

Now, question. This guy says the gun was new, maybe he believed that. He says he never shot it. It IS in extremly nice condition, so if its been shot I believe it was not much. However, I was wondering about the amount of "play" that is acceptable in the barrel when you pull the slide back? Side to side and up and down there is almost none, but the barrel slides back and forth almost half an inch with the slide locked back. Is that normal? Someone told me excessive play in the barrel was a sign of wear, but I dont know what's excessive?

Does it move back and forth when its in full battery?

SOA packs heat next to the keyboard just in case that m4d l33t lamer nails him one too many times...

That's how the 1911 operation works. Though how much it could move is not known to me (offhand, mine is 200 miles away).

The barrel is supported in three places, just infront of the back face on a two pin roller (looks like a figure 8 sorta), ontop of the barrel will mesh with teeth on the inside of the action, and in the front in the housing of the slide. What happens is you pull the trigger, the bullet fires.

Then the bullet pushes back on the slide. Since the slide and the barrel are meshed together with teeth (like a flat gear), when the slide goes back, so will the barrel. The barrel rotates back a bit ontop of the figure 8. The barrel is connected to the top pin, and the bottom pin is connected to the insides (I forget where though). So the entire barrel has rotated back and down a little bit. This literally makes bullet feeding much easier. The bullet would have a longer distance to travel if the barrel didn't move, plus have to get in at an odd angle into the chamber.

But since it rotates back, the bullet has to slide less and go in at less of an angle. Thus making feeding the bullet better.

So the spring kicks the slide forward. The teeth ontop of the barrel mesh up with the teeth on the top of the slide and they both travel and lock forward by the action of the spring. (They aren't literally locked forward, but some actions of guns do lock forward. The 1911 slide can be pulled back at any time.) So the barrel is now integral with the entire gun and stable.

ooz, I make sure I have nothing heavy enough to damage my computer or my monitor close at hand when I fire up AH. With my temper, I'm too likely to put something through the monitor lol. Trust me, the guns are safely out of reach when I sit down for flying time.

dumped the mag and ejected the round in the chamber and locked the slide back on the kimber sitting near my coffee.. bout an eighth of an inch play... My old Colt seemed to move back a lot but shot fine.

I can't feel any play in the slide on the kimber side to side but the old WWII colt would actualy rattle.

zero play in the barrel/bushing area of the kimber but the old colt was pretty bad.

Actually measured it last night, its more like 1/3 of an inch back and forth movement, so I guess thats alright. Its not like this is going to see millions of rounds put through it, although I will be taking it to the range alot for the next couple months to get used to it. I pulled the slide off and broke it down, everything seems to have pretty tight fit everywhere, so I'm happy. I mean, even if it had been a little worn, the gun with 2 mags and the Norinco cleaning rod for 250 bucks total cash layout aint bad. According to one of the websites I was looking at last night for info, the Norinco's are supposed to be identical copies of the Colts (as far as parts interchanging) so it should be easy to get parts for if needed. I'm heading to the range today after work to put some rounds through it and see how it fires. Thank goodness I started early on reloading.

I've got 100 rounds of my loads to play with, and a box of factory ammo as well. See how my loads group compared to the factory stuff.

Ok here we go. I shot 2 mags of each type before switching, to give me a chance to get used to it. First tests from 25 yards. Was going to do a second set of tests from 50 yards, didnt get to it.

First up were my low end reloads. Using Titegroup powder and 185 grain RNFP bullets. First 7 went high and right, all inside the sillhouette but only 2 in the kill zone. I think it was my grip. Next 7 I paid more attention and I was indeed twisting the gun and worked to try to modify this. 4 in the kill zone, the other 3 were all over the place. Weirdly enough, its the first two and last two that landed where I wanted. Maybe I tighten up after a couple shots? Need practice.

Next were the factory loads. 230 grain +P Cor Bons "Performance Match" grade. Recoil slightly stronger, better grouping but still a little high and right. All 14 within a spread on the silhouette from mid ribcage to the shoulder, about 5 in the outer kill zone. To me, thats all over the place. Need to work on getting feel of this thing, I'm used to my revolvers that dont move lol. Been too long.

Last 25 yard test, handloads with 200 grain RNFP and Titegroup powder. First 2 in the kill zone, almost dead center, but the rest were all low. Much tighter group though. All of the final 12 of this 14 ended up in a 6 inch group about 5-6 inches below the kill zone. I did seem to have better control, but I'm not sure if it was me getting used to the gun or this round worked better for me as far as dealing with the recoil.

Place was getting crowded, so I put off the 50 yard testing. Besides, I'm not accurate enough at 25 yards yet to be happy with it, I need work with the gun before I start trying distance shooting. Going back tomorrow.

shoot from sandbags.. the lighter loads should not have shot higher than the 230 grain ball ammo... powder differences can change that slightly but... as a rule..

I use AA#5 with both FMJ and cast lead 230 round nose. In the gun right now is federals 230 grain hydro shocks.

I have never noticed a 45 auto to have any recoil to speak of..

Maybe not. Ive shot only revolvers for so long its hard getting used to something moving in my hand lol. I agree though, I need to shoot from a rest next time and remove my twitching from the equation.
