Yes, that is a problem. But some things are universal. Trigger control and a proper grip are such things. The only really SA specific issue is how the gun fits you and the proper style of hold.
First off are you a one handed or two handed shooter? A one handed shooter with an SA gun should have their pinky tucked down under the butt of the grips. This pretty much automatically positions their hand at the right position on the gun. Otherwise the tendency is to grip the SA too high up.
The rest is pretty much universal;
- Hold the gun firmly but don't white knuckle it. If you hold too hard it becomes difficult to isolate the motion of your trigger finger from the rest of your grip. Above all you want to support the gun with NO MOVEMENT other than the trigger finger.
- Don't pull the trigger. Instead build pressure smoothly and let the trigger move as and when it wants. Just keep following it and building the pressure smoothly.
- Always "follow through" on the trigger. This means don't just pull to the BANG!. Pull through to the rear travel limit and hold it there. When all the smoke, noise and recoil disapates the trigger should still be on the rear travel limit.
- Focus on the smooth pressure build and pulling to the stop. The BANG! should come as a surprise.
- Do not EVER try to fight or control the gun in an attempt to limit or control the recoil. You'll never get the timing or effort right and all you'll get is a pattern instead of a group on the target. Work at becoming a totally stable and immovable "stump". The ONLY two things that should be moving on your body when you're shooting is your heart and your trigger finger. EVERYTHING ELSE stops for a moment during the trigger pull.
Some dry firing can help. Use dry firing to work at achieving all the goals set above before you try the whole enchilada with live ammo.
If you're performing the basics noted above and if your trigger finger is pulling the trigger from the right placement you should be able to hold your sight picture on a spot on the wall and when the hammer drops there should be no up, down or sideways movement of the sight picture. Not so much as a wiggle even when the hammer falls. This indicates a desirable neutral trigger pull with no flinch or steadiness issues.
When you get to the range do a few of these dry fire sight picture on the target you'll be shooting at to get into the groove. Then load some ammo and shoot as if you're still dry firing. Wash the fact that you're about to feel a big BANG! out of your mind and concentrate on the smooth pressure build and proper follow through. If you don't have a flinch or other issue the groups will be small.
Most Blackhawks tend to be bigger bore guns and if shooting stout loads a flinch can be a real issue. Perhaps find or load up some light loads and work on your steadiness.
When I shoot the big bore stuff with stout loads I can actually feel myself leanding towards a flinch. It shows as my eyes feeling like I'm wanting to blink in anticipation of the BANG! or my hand wanting to move or even my trigger finger "knowing" that I'm just about at the right point and pausing. None of these things are good and the group will suffer for them.
A GOOD shot will happen when it feels like you're just doing another dry fire exercise and the BANG! sounds and feels like someone a couple of bays away took the shot instead of you. When you get to that point you're going to produce some nice tight groups.
