Quick Look at the CP1-M CO2 Pistol

Bought a .177 cal CP1-M from Mrod Air.  It arrived last Thursday.  I've been a bit pressed for time, but I wanted to get a few pics up to maybe help anyone on the fence about getting one.  There aren't many images of the gun online--especially with the changes Mrod requested.

Grip is uncheckered.  I was grateful.  I thought the checkering on the original version cheapened the look of the gun. 

I'm sure I'll refinish the grip in the future--probably with some stippling.

Trigger guard is on the small side.  If you've got big hands, this is gonna be tight.  I've already got a chunk of aluminum on the milling machine table.  Can't see it without removing the grip, but the trigger is drilled and tapped for a sear adjustment screw.  A factory oversight/miscommunication prevented said screw from being installed  The thread is metric.  It's M3 x .5mm.   Mrod Air didn't catch the oversight on the screw until after the guns arrived.  Apparently, screws are being mailed to all who ordered.  If you can't wait, you'll need one about 4mm long.  It makes a big difference.

Front sight is steel.  It's screwed to the muzzle weight, which is in turn, attached to the barrel with a set screw.

Rear sight has a metal blade attached to a plastic body. 

Haven't checked, but the bolt and bolt handle look like stainless steel.

Here, I've removed the single shot tray.  It slides right out from right to left.  It's retained by a small rare earth magnet.

The aluminum single shot tray.

Bottom view.

One of the 9 shot .177 cal magazines.  Black anodized aluminum and plastic.

Installed.  These are also retained with magnets.  You can swap back and forth between the single shot tray and a magazine in, oh, about 5 seconds.

Can't tell from this angle, but the magazine presents absolutely no interference with the sights.

For comparison's sake, the CP1-M magazine is on the left next to a Benjamin Marauder mag.

Quick notes:  The pistol points more like a European 10 meter or .22 cal target gun than a Colt 1911.  The grip angle forces you to drop your wrist to line up the sights.  I'm a big fan of 10 meter match guns, so I like it.   It was very quiet at first.  So quiet, I was skeptical about the velocity.  A quick check on the chrony showed it to be in the mid 360 fps range with RWS Hobby pellets.  Added a second spring inside the hammer spring, and the velocity went to 518--525 fps with those same .177 cal Hobby pellets.

I'll have some additional info here in the next few days.  Thanks for reading.

Thanks for the quick review and detailed break down of the CP-1M. I think I am one of the few people in Canada to have one since there is no importer in Canada yet. The .177's are too fast and would have to become a RPAL weapon meaning a restricted weapon only allowed to go from the range and back home. No fun for a pellet gun shooter!

After shooting it more can you share with us the pellets that it likes best??
Right now I am just using Crosman Premier hollow points in .22.

Thank you Much!

Mechanical processing is too rough. The magazine jam will be your nightmare. The worst situation is pellet head in the barrel and skirt still in the magazine.

I got mine from mrodair last week, and I'm pretty impressed. The trigger is very smooth and crisp, but loading is definitely rough, requiring quite a bit of effort using wadcutters. I haven't torn it down to inspect the ramp, but in the action it looks like it could benefit from some polish. Or moving the seal from the barrel to the bolt as in the crosman 2300 and similar.
