@cslinger, let me ask you this: Would it make sense to pick up a gas pistol pellet gun, learn to shoot that and maybe then give the Impact another chance? I'm not likely to get much $$$ for the Impact, and from looking at Air Gun Depot and Pyramyd Air, I a decent gas pistol rifle shouldn't be that expensive.
When you say "gas pistol" I assume you mean C02 pellet or BB. If not then Airsoft????? I will try to quickly address all three.
C02 Pellet - The vast number of C02 pellet pistols these days are basically replicas. I find they tend to have pretty horrible triggers, a loud report and between the trigger, sights and volatility of the C02 (if its warm its shoots faster, if it colds it shoots slower, the more you shoot it the more it cools etc. etc.) I don't find them very accurate at least in my experience. They can be FUN but for me I don't care for them all that much.
C02 BB pistols have all the same downsides as well as the lack of accuracy and ricochet potential a round steel ball brings to the table. They do, however, typically have a fairly realistic blowback action and can be insanely fun to shoot. Again accurate not so much, fun yes.
Airsoft-Airsoft is actually a great training aid. You have a relatively safe projectile (they will still welt you and can injure an eye so still treat with respect you would a firearm) but they allow for cheap presentation training, instinctive fire, etc. etc. With the right equipment you can do force on force stuff. Again, accuracy is not going to be there, but they can be FUN.
If it were my money I would go with the following tiers of thought.
Tier 1 - REAL GUN MONEY($350-$600) - Buy either an HW30 or an HW95 and replace your rifle. The 30 is a sublime shooter and its just an amazing, fun, easy rifle. The 95 is much the same but with more power if you want to reach out or hunt. It will however be tougher to cock then the 30 of course.
Tier 2- REAL MONEY BUT GO PISTOL KEEP THE IMPACT (Around $280-$300) - Buy an HW40 or Beeman P3. These are single stroke pneumatic pistols that are insanely accurate, fairly easy to shoot and give you a vaguely modern firearm feel. Think Walther P99/PPQ grip. Now these are not dirt cheap but they are excellent.
Tier 3 - ALMOST CHUMP CHANGE YOU CANNOT AFFORD NOT TO DO IT (Around $100)
- Beeman imports a Chinese copy of the P3/HW40 call the P17. It's like 45 bucks. You can have that and like 4,000 rounds of GOOD ammo for about hundred bucks. So keep the rifle, learn to tear down, check/replace the seals (should be cheap) and get a great pistol to dip your toes into the water.
I know money is different for everybody and I know disposable income is not always easy to come by. That said, IF you are able to I really would suggest a nice German or English Air Rifle. Yes they are REAL gun money but as hard as that is to swallow for us gun guys, most folks are amazed at the quality, fit, finish, trigger and accuracy you ultimately get. Again this is just my personal observations and experience talking and I don't claim to be in your shoes, but if your only barrier of entry is a mental one.......give a try I think you might surprise yourself.
Take care, shoot safe,
Chris
