Ruger P90DC Problem

(1/3) > >>

Howdy All!  Need some advice...

I was out at the Bullet Hole yesterday, shooting some reloads I have been building up, and ran across a problem that I have never had with any type of weapon before.

The weapon is a Ruger P90DC 45ACP.  Good gun, never heard any bad things about them, but mine was used when I got it so what may have happened to it before I got it is unknown.  Here is the problem.  I cant seem to get the slide to lock all the way to battery.  Even when manually pulling the slide fully and allowing it to go forward on its own.  Its easy enough to push it into the locked position, but after firing a round it ends up about 3/8th of an inch short of fully closed.  Factory loads also do this, I tried some White Box. 

A friend thinks it might be a weak slide spring and suggests putting a spacer in on the spring guide to see if that fixes the problem.  Personally I have never heard of that being done, but it sounds logical.  Another option of course is to buy a new slide spring for it, which I am seriously considering. 

Suggestions or comments?

Replacing the recoil spring is were I would start, especially since its unknown how many total rounds have been through the gun. Also give the chamber a good once over looking for any fouling that may be building up.

Regular replacement of the recoil spring is generally overlooked by most gun owners. Manufacturer suggestions vary but I replace mine every 2500-5000 rounds depending on the gun.

Thanks Shawn.  After posting that this evening I thought about that whole spacer idea and tossed it.  Seems to me that a spacer would prevent the slide from cycling fully, and of course a replacement part at MidwayUSA is just about $3.00.  Go figure.  ::) For that price I think that's the way I am going to go.

As durable as those guns are, you can always use it as a back up hammer......

Just to be clear, the gun only does this with a round in the chamber?
