Just finished upgrading the sights on my 45 Colt Rossi Puma '92. 20" octagonal barrel. Put on a Marble's tang sight, taller front gold bead sight and fold down rear sight. The front sight and tang sight went on easy.

The rear sight was loose in the dovetail, which had been reported by other owners previously. I put a bit of JB weld on the front side and the bottom of the base, let it cure overnight, and drove it into the dovetail. Went in well and seems to be solid.

The rear sight is adjustable for elevation and windage, as is the tang sight. Not sure why I'm working at getting this thing to shoot good at 100 yds since I have a gun or six which work just fine with those new fangled scope thingies.

Too wet and windy for the range yesterday and it looks like more rain for the next week.

Bought the gun for fooling around on the pistol range, now I'm thinking it needs to kill a deer.

Pics, we need pics :-)

I love lever guns and my two Pumas (20" Octagon Barrel, and 16" Carbine) both sport aftermarket marble Arms sights. If I may ask; why did you go taller on the front sight? With a tang sight you may have gained some range going with a shorter front sight. That's about the only issue I have with mine; is that with my current cast load, I only have enough elevation for about 200 yards with the tang all the way up. One of these days I might get one of the improved tang sights with the longer range posts. Might even be cheaper to go with an even shorter front, scratch that...it would be cheaper to go shorter on the front. But I have no illusions about hunting past 125 yards with a .44 mag anyway, Just want to be able to bang steel at around 300yds without having to using SWAG adjustments :-)

I'll wait to shoot some fullhouse 200gr XTP loads I made up before I change anything though. The lighter bullet might give me the range I'm looking for. But like you I'm waiting on the weather to cooperate, plus I just had lower back surgery on Tuesday so I'm really not in any shape to be shooting, plus the Meds I'm on say don't operate dangerous machinery LOL.

Went with a 1/16" Gold bead, folding rear, and standard tang on the 20" Octagon Short rifle. And a 1/16" Gold bead, and Bullseye Rear on the 16" Carbine.

I put a Marbles tang sight on my .45 Colt Puma as well. The original rear sight is/was crap. 100 yards is a bit long for the blunt .45 caliber bullets I have been shooting. I am trying out some 280 grain LBT-type Long flatnose slugs at about 1000 fps. tomorrow to see if I can tighten up the 6" groups I have been getting at this range

Mine shot high. Real high. The original rear sight all the way down, the tang all the way down, still high. Got a taller front post and I can get it to shoot low if I want.

Only got to shoot at 25 yards today, the rifle range was having a competition.

I like the new rear sight, but am concerned that it is a bit delicate for knocking around in the woods. Might try one with the ladder ramp for hunting.

I've been playing with loads. Got some Beartooth 340 gr running at 1,200, but they kick like a mule. Had good luck with some 250 gr LRNFP running just over 1,000 that worked good.

I've never used a peep sight before. Not used to it and not sold yet. I was hitting better groups with the regular rear sight. I'm not giving up on it yet.

I'm having a lot of luck with Dr. Skinners rear sight peep replacement:

www.skinnersights.com (http://www.skinnersights.com)

Quick on target and retains the guns orig profile. I did have to file down the front sight blade a bit to get the holes where I wanted them when this peep was in the center of it's vertical travel.

Which size base?

Is that on a Lightening?

If that question was directed at me ... that photo is a "stock" photo from Dr. Skinners web sight, meant just to show the sight. The Rossi's I believe use the .390 dovetail.

I was a little leery of a peep that far forward of my eye ... but it works just fine!

robctwo, Nice looking rifle. You will probably get used to using the peep sights. The trick is to focus on the front bead, the bead will naturally center in the rear peep. Center of bead is where you want the bullet to strike, that is why most folks get small front beads.

Thanks. I got the bigger bead, may need to go smaller. We'll see as time goes on. Fun gun to tinker with.
