to make loading the magazine i use a clear plastic straw to load it it is easy and quick

this BB gun is ok for plinking cans at 10 to 20 feet it's not spot on because it,s only 480 fps and has a smooth barrel but over all i like it

i like it because i can keep my trigger finger in shape when i can get out to the range

This wasn't worth the price (under 50) I bought it because bad shoulders don't allow me to cock the air rifle I had for squirrels. I haven't hit one with this, even within a dozen yards. I have emailed the seller.

Ease of use/loading. Light

Each bb goes off in a different direction, very unreliable

By StevenUSAOctober 24, 2020

good for plinking cans, a lot of fun with a laser sight.

Reliable, smooth reload, good handle (secure because it is designed to not be removed unless clip is first removed), accurate.

the picatinny rail didn't work, but the weaver did. trigger pull could be softer.

Don't buy, this model is a lemon.

Crosman has excellent customer service and has since made things right.

It has a defect where the firing mechanism doesn't work and this airgun won't fire at all. I pull the trigger and it fails to fire (the safety is off) and the BBs leak out of the firing tip, I sent the first one back for a replacement which I promptly received and the second one had the same problem. Also it's made out of cheap flimsy plastic and the magazine release button broke only after using it four times.

Save your money for something that conveys a better replica of the beloved 1911 hand gun. I thought for 30 bucks it could not be too bad, but when received and examined, I was shocked at the lack of realism and that Crossman would put its name on it. I have not loaded or fired it yet, but I don't expect any thing special or outstanding.

It is called a BB pistol but the chart says it is for pellets. Which is it, BBS or pellets.

asked Russ from USA

Does it come with co2

asked Kemarion from USA

Is the mk 45 a replica

asked Cindy from USA

To my knowledge Crosman has yet to produce anything even Crosman themselves would call a "replica" of any "firearm". Some of their products "resemble or based on" real world firearms. Producing "replica air guns simply doesn't fit within their existing business model. Functioning budget friendly air guns does appear to fit well. I'd bet there are few "replica" airgun Co.'s that hope Crosman remains in that lane.
