I've been considering the purchase of a SP .22/.32 Bullseye combo. One of the main issues as you guys know is mounting rings for a red dot especially on the .32acp since the rings are known to slip. I was checking on options today, I spoke with both Larry's and BME, both said they no longer make scope mounts for the Pardini. Larry suggested I call PardiniUSA as they might offer rails.

So I spoke with Vladimir at PardiniUSA. He said they were about to release an updated SP for Bullseye use with an integrated picatinny rail in the barrel shroud. It wasn't clear how far back the rail would extend however he did mention possibly having to use 2 scope rings on the front half of the red dot so sounds like it wouldn't extend as far as the old Larry's rail. He mentioned this would get the dot lower than if using a rail adapter. My only concern without seeing more info is possible balance issues if it requires the dot to be mounted too far forward, some of this could be offset by removing some of the 6 counterweights. On the plus side this will allow using a dot for each caliber so you won't have to juggle adjustments as much, just your standard 25 to 50 yard adjustments. Plus you won't have to buy an additional $200 worth of rails and possibly have to have a brand new gun drilled & tapped.

Vladimir did seem a bit defensive though. When I mentioned scope rings slipping he blamed it on people using the wrong scope rings (not Pardini rings) however I swear I've heard of issues using their rings as well. I also asked him if there had been any adjustment in the slightly oversized bore on their .32acp for the new model, he stated it was a propitiatory tapered bore however it seems if it were tapered when people slugged their bore it would measure the smallest diameter but I hear most barrels measure out close to .314".

Anyway, its good to see Pardini is improving their product for the US bullseye market. I'll be eagerly awaiting pictures and reviews from early adopters.

zanemoseley,

I would like to see the integrated Picatinny rail run from the muzzle all the way to the very back end of the pistol. This would then allow one to place the red dot sight at the balance point that works best for them. Yes, removing the 6 counterweights could help with balance issues. But what do you do if this is not enough?

I prefer having the weight of the pistol balanced back into the hand. Other shooters favor a muzzle heavy feel. A full length rail would accommodate everybody!

Actually based on the measurements we have taken, having a scope mounted at the front brings some of the balance from the muzzle (becasue of the weights) back to around the area of the trigger.

If you remove the weights all together, then the balance will be a little further back.

It seems like it would be relatively straight forward to attach a sight rail to the shrouds on an existing SP/HP? Attach from the front sight with another screw back an inch or so. Then, one could determine the length they wanted.

Right up front, I am a fan of the Pardini BE edition and shoot both 22 and 32ACP. It is a very good system, but not perfect IMHO.

The barrel with a short Picatinny shroud is a post hoc fix for American BE shooters to solve the wandering scope ring issue (scope rings do not stay fixed with the recoil impulse of the 32 ACP because the gripping surface, the narrow groove on topside of pistol's frame, are insufficient to fix rings tight). Who would have guessed, especially with 60-grain bullet of the ACP versus 88 or 98 grs with the S&W L caliber?

The best design correction would be incorporating a Picatinny rail into the pistols frame, where the cross-slot feature would forever fix the problem of scope rings failing to hold position under recoil. It could be designed to still use iron sights but have the option of steadfast scope mounting. Maybe sometime.

I've learned to live with scope wandering by ignoring it. I only use the 32 in 2700s; otherwise I shoot a 45 for centerfire 1800s. I have my front scope ring positioned all the way to the rear of the frame groove (see image) which more or less enables me to reposition a moved scope to same starting position. So, when the rings slip, i.e., move about 0.5-inches forward under recoil (only after shooting a 90-round match), the zero isn't significantly changed (but I re-position and re-tighten rings after one match). The rings are Warne low mount Picatinny rings, internal cross-slot bar removed, bottom of feet filed to sharpen inner edge and thence grip tighter (?).

I used to use the 32 for all centerfire stages in 1800 matches, but discovered my 45 skills suffered. However, the little 32 is so fun to shoot in a 2700. Honest be fair, I probably wouldn't buy the 32 today (but I am keeping mine).

I've tried mounting both rings on the front side of the Matchdot II, which had an unexpected consequence. While the pistol was setting on a rest (and I was fiddling with a chronograph and notes), a sudden strong wind gust blew the pistol off the rest, off the range table, where to my utter, cringing horror, it banged off the concrete floor in a sicking thud. (Loud cursing). Remarkably, the gun landed on the bottom rear corner of the grip, cracking it; otherwise, the pistol suffered no cosmetic damage (a few scratches on scope sight-pattern selection knob). Can live with that, but note the new grip.

The unexpected part: having both rings on the front of the red dot and the force of the impact caused the Matchdot II to unscrew (the controls that were on top of the sight were now on the right side). Cursing, cursing, and more cursing. Luckly, I did not lose nitrogen and was able to retighten front part of the scope by turning it counterclockwise.

Maybe accidents this are a senior shooter issue. I don't know. It wasn't even a windy day; hell, it was morning. I heard not the sound of tornado, thunder, or crashing plane; may be the gust was a random puff, albeit a strong one. Pistol netherworld, dipnet

Why couldn't you buy another scope ring, cut the upper part off to make a "block" to install on the rib to prevent the rings from sliding under recoil?
