CP1-M pistol first impressions

[Ribbonstone]

Have an unexpected day off.

 Other than a lunch date, will work on this conversion (simple as it is).


Going to turn this:



Into this (manipulated photo):



May as well make the upper stock section thinner while I am at it.

Then, while the first coat of finish cures, will start tacking the metal work. Will shorten the barrel, shorten the shroud, and have it all end up about like the photo at the bottom.

Power isn't th goal...accuracy and shot count are...so don't really care how much velocity/energy it loses (it's already low-slow-n-quiet).

Doubt I'll go with finger grooves, but I will get rid of that useless rectangular shelf and have the grip lenght end about 1/8"-1/4" below my hand.

Well, might as well chime in- I'm also in the process (very early in, I might add) of resculpting the grip. Don't know who designed these but IMO they should stick to farm implements and leave pistol grips to those who shoot pistols! 

@rrdstarr That's coming along nicely! Don't know if finger grooves are something I want to try or not, given my less-than-stellar woodworking skills. In the photo below the pencil lines are barely visible that I made based on the tracing from my Ruger Mk 3:

Almost where I want it.  There is plenty of wood to carve off to get a good match style grip.

That is nice work. What tools do u use to shape the finger grooves?

[rrdstarr]

Ridgid drum and belt sander.
Also have a Foredom for detail stuff!

[Falstaff]

Wish someone would list one in member classifieds. I'd grab it.

Didn't mean to display the 9 1/2" Damascus tanto!  But it is another work in progress, just waiting for Cocobolo to arrive!

Paul,

They're still $89 shipped.... http://yhst-139878093962642.stores.yahoo.net/mrcpmushco2t.html

Not a bad price for what it is.

[Falstaff]

Yeah but Mrod air doesn't take paypal (I even called and talked to the owner) and that is where I have all my funds for this hobby. If they did, I would have two of these in .177 and .22 and a plinkster as well. That's why I am hoping someone posts one in the classifieds someday.

Thank you anyways, though.

Perfect, Thank you.

I have a drum sander and Foresum tool that my dad left me years ago that I do not use a lot.  Thank you and once again, very nice work.

Clap Clap Clap. Bravo Jason. I think the o-ring buffer (Bstaley) mod is the way to go. Still cold in my basement (56) so the velocity isn't as high as I'd like. But I was able to get 90 shots above 300 FPS and averaged 424 fps. Total energy was still crappy (I think 260 FPE) but I'm happy with this average FPS and shot count, especially for such a tame pistol.

My o-ring stack ended up at 1 016 O-ring, and 2 113 O-rings, all 70 duro, which makes perfect sense since every one of these pistols are so much different.

I had s-laughtered my stock spring, so I called up MRODAIR and they sent me one right away along with the missing spring guide that I had emailed them about when I received the pistol (LOL. Just kidding.  We all know better). I actually found these springs on Zoro and thought I'd give them a shot, they are much longer, but cut to length they are almost a dead ringer for the stock hammer spring on these pistols. Super easy to cock, about .050" preload, works great. I'd recommend anyone in need of some 3/8" OD springs with not many coils to give them a shot (they are 6 coils/inch).

[nervoustrigger]

Very nice, I'm glad you figured out an arrangement that worked to extend the shot count.  Considering the recent $12 / 40pk CO2 deals that have been going on at Amazon and Walmart, it's nice not having to swap cartridges so often even if the expense is insignificant.  And I think 260fpe at 56F from an 8" barrel in .177 cal is quite good.  I wouldn't be surprised if you surpass my 310fpe at a similar temperature.

Man, that first part had me confused for a moment.  Thought maybe you briefly inhabited an alternate reality.

How does the grip feel? I have very large hands xxxl gloves. Yea I'm a big ol boy. Most pistols I've tried feel like kids toys in my hands. Do these grips have some meat on them? Thanks

"Like I'm holding a 2x4" is the most accurate description I've seen. My hands are long and skinny and it fits fine, if your hands are wide, you may not have enough room between the palm shelf and the trigger.

The diameter is about 5-1/4" at the top of the grip, widening to about 6-3/4" near the shelf at the bottom of the grip. They're larger on average than my Glock 22 (5-5/8" top to bottom). But for me personally it wasn't just the diameter of the CP-1M grip- it also sports too much angle, the shape makes for a too high hand position and accentuates the 'broken wrist' hold it makes the shooter use. The grip is too far from the trigger to permit a decent hold further towards the middle of the grip and the plank across the bottom serves no purpose for my way of shooting.

Hear! hear! Once I start carving, that is going to be the first thing to go.

[cobalt327]

I just p'shopped this, it's rather crude but does show what I was trying to say regarding the distance from the trigger and the weird shape to the back side of the grip compared to a Ruger Mark .22- which is already about as slanted as any gun out there, while still being a comfortable gun in hand (to me anyway). The triggers of both guns are laying one atop the other.

I dug out my 177 cal cp-1m and tossed a few across a chrony inside.  my trap is 15 feet from my table.

first 2 shots went into the same hole.   I actually pushed a rod down the barrel to be certain it fired.  LoL

I am using a cheapie crosman copperhead red dot on it.  I like the very small form of that red dot and with 2 levels of lighting it works well enough.  only downside is the dot covers the 1" bullseye (though part of that is my old @@@ eyes), so i was quite surprised it literally stacked the pellets.   3rd shot tore a ragged hole and then i began to adjust for zero as she was a tad left and low, though i only adjusted for the windage.

I was shooting the 6.9 RWS pellets and getting 516 fps average over 5 shots for 4.08 FPE.  chairgun says i still have a tad over 3 fpe at 25 yards.

OK, so I paid the $89 cover charge for this thread (thank you enablers) and received  my CP1-M the other day...So far happy with the pistol.

The earlier comment of the grip feeling like grabbing a 2x4 is pretty close...so my question is: have some of the posters that were mapping out changes to the grip done any reshaping yet?

I'm new to the target pistol configuration so I'm not sure what features to keep. I do want to use this pistol to learn a one hand hold so I don't want to start carving it in the direction of my 2240 or p17.

My hands are reasonably large so in general the grip fits OK but feels like it is contacting in discrete points and I don't think I grip it the same way each time.

So any guidance I could use, mostly in what to keep to make it consistent with a target grip?

Finger grooves should be a start, minor reshape to get more full contact? deepen the thumb groove?

Thanks

Check the bottom of page 4, that is what I have done, so far.

Rick,

I saw those, great design. Did you start with new wood rather than the original grip? Could you take a picture of the grip in your hand at some point?

If you don't mind commenting on some of the features you put in and why.

Sorry for the newbie questions.
