Actually Yes because of the length of the longer barrel plus it is capable if reaching 600 FPS It's a proved airgun and has been around, in one form or another since 1977. The gun is only part of the equation for accuracy. The pellet is also important. Try
Beeman H&N Match .177 Cal, 7.5 Grains, Wadcutter or another match pellet. Also learn to breathe correctly and pull the trigger correctly.
Crosman doesn't modify existing models. But you can order a custom model made for you. See the link below. Also there are several airgun smiths that do modify existing airguns. They do all kinds of modifications and repairs. See the link below.
Crosman guns are consistently made very well. The 1377c is no exception to this. As a point of fact, the 1377c's simplicity and reliability are part of the reason it has maintained in production since it was first released. Also, as a note, if you plan on buying on of these, do a little looking for "custom 1377c's." There is a fairly large customizing community that has done some really cool things with their 1377c's!
Because of the way the 1377 is designed it is not possible to easily attack a laser sight to the pistol underneath. There are a few custom shops that manufacture a custom breech that is longer than the stock breech. Crosman even offers one. You might be able to attach one there. I've attached a scope to one of the 1377's using Crosman part (459MTC) it a Crosman Airgun intermount for scopes. Click on the link below to see the Crosman accessories.
It all depends on what you want to shoot with it. Plinking, Target or Hunting. Then how much can you afford. Inexpensive air guns are as cheep as $20 up to over $500. A good airgun not AIR SOFT, you asked about Air Guns, there is a difference, will shoot pellets. Forget about BB guns they are inaccurate. well made Air guns have rifled barrels. These are the grooves that make the pellet spin and shoot straight. BB guns have smooth barrels and the BB's wonder off target. Your question was about guns so I assume that you are not asking about rifles. Guns have less power than rifles and are a little less accurate. However there are some excellent Airguns in production. The best Airguns are of the "PCP family" these are competition air guns and very accurate. PCP (Precharged Pneumatic) air guns start around $500 and go up from there. Check the first link below or Link #2 these are two of the best online airgun shops that I know of. Now if you want a less expensive but an accurate airgun I suggest looking at the single shot Crosman 1377c for around $55 or the single shot Crosman 2240 for about the same price. The 1377c is a multi pump and very accurate, the 2240 is a C02 airgun and fun to shoot. The Crosman 3576 ($50) is a 10 shot, modeled after the "Colt 357." I suggest the you look at the two web pages and read the reviews on Pyramydair and find something you and afford.
Basically the same pistol. The 1377 American Classic is rated at 560 FPS the new 1377c is rated at a little over 600 FPS. The loading chamber is slightly different the new one has a bolt action. The original 1377 you had to pull the back knob to cock the pistol, the new 1377C the bolt cocks the pistol. Both have a rifled barrel, both shoot .177 cal pellet. I own both of these pistols and find them to be fairly accurate.
First variation has manual cocking and steel breech 1977-81 Second variations had plastic breech 1981-96 After that is was the 1377C model 1998 to present
Not a good Idea. The vibration and handling it will most likely make it come off. Also if you mount it just a little off you will never get it to align with the sights.
Eventually everything wears out. But if you maintain it, it will last you for years. I own both a newer 1377c and a very old (and I do mean old) 1377. Yes I can tell the difference in how they pump, but the old 1377 (American Classic) still hits the target. If I had it rebuilt it would be like new. But why, it still performs well.
It might still work but you probably shouldn't trust me cause I've never painted any of my air pistols before.
Beretta Elite Fires at 480 FPS (Feet Per Second) Beretta Storm Fires at 380 FPS. The Crosman 1377C (Amreican Classic) Fires at 600 FPS. It puts both Berettas to shame.
The Hand grips "Yes" they come off easily. The forearm does not come off. The Hand grip is designed to come off so you can attach a rifle stock to the 1377 and convert it into a carbine. Removing the spraypaint might be a little harder.
320 in a pellet gun is average. there are a few that have a higher FPS, but anything that fires between 300 - 400 FPS is normal for a C02 pistol. Rifles on the other hand currently are made to fire above 1000 FPS. The Crosman 1377C fires above 600 FPS but you have to pump it 10 times and it is a single shot pistol
