Wow! There seems to be some confusion here.

1. Recently shot a DR match. They weighed triggers DA looking for at least 2.5 lbs. Of course every gun would pass that DA. I read the rule as minimum 2.5 lbs. To me that would be SA.

2. In a conversation about revos in general some held firm on trigger weight for .22LR revo would be 2 lb., "all" other revos would be 2.5Lbs.

2. My feeling, perhaps wrong, is that the 3.5 lb rule applies to "all" .45 caliber firearms, regardless of whether they are semi auto or revo, except of course EIC CF which is 4 lbs.

So the questions are, in weighing revolver triggers for NRA PP/BE and CMP EIC are they weighed in DA or SA mode? Next, must a .45 revolver meet the CF revo standard of 2.5 lbs or the .45 standard of 3.5lbs?

Revolver trigger pull is weighed in single action mode for NRA and CMP matches, not double action.
A .45 caliber revolver is 2 1/2 pounds not 3 1/2. Only .45 semi-auto pistols are 3.5. (4 lbs for any EIC Service Pistol)
.22 caliber revolvers are 2 pounds, not 2 1/2, just like semi-auto .22's.

See NRA rules as follows:

3.3 (a) for DR trigger weight
3.4 for .22 revolver weight
3.5 for CF pistol/revolver weight
3.6 for .45 pistol revolver weight.

1. Yes, they should have weighed in SA for the DR match.

3.3 Distinguished Revolver - The revolver must be capable of chambering and firing a 158- grain round nose or Semi-Wadcutter .38 Special cartridge. It must be a factory manufactured revolver with no external modifications except for stocks which may be modified or changed because of the size of the competitor’s hand or to facilitate loading. Except for stocks and the honing of the sear or sear notch to make a more crisp trigger, and maintain a 2 1/2 lb. minimum trigger pull, no external or internal modification may be made to the revolver as manufactured and sold by the factory of origin. No parts may be removed from the revolver, either externally or internally, nor may any part be added, with the exception of milling the cylinder to accommodate moon clips. Specifically prohibited is any system of recoil control based upon compensators, barrel venting, barrel porting or weighted grips. Exposed holes that have been drilled and tapped for mounting of a scope are not considered to be an external modification.

(a) Trigger- Must have single and double action capability and must be capable of lifting 2 1/2 lbs when the revolver is cocked for single action firing. Triggers will be weighed. Any trigger, sold by the manufacturer of the revolver, without modification, may be used.

2.  Yes, .22 revolver trigger weight is is 2 lbs.  Doesn't say SA, but come on, how do you know the pull isn't less than 2 pounds unless you make the revolver have its lightest action mode?

3.4  .22 caliber Pistol or Revolver – The .22 caliber pistol or revolver, as described below shall be used in the .22 caliber precision pistol matches. Any pistol (single shot or semi-automatic) or revolver chambered for .22 caliber rim-fire long rifle may be used; barrel length, including cylinder, not more than 10 inches. Trigger pull not less than 2 pounds. Any sights, including telescopic, are permitted with the exception of those sights that project an image on the target. Open (metallic) sights may be adjustable but not over 10 inches apart measured from the apex of the rear sight to the apex of the front sight. Any sighting device programmed to activate the firing mechanism is prohibited. All standard safety features of the gun must operate properly.

3. No, .45 revolver weight is 2.5 lbs, .45 semi-auto is 3.5 pounds for NRA competition.  All service pistols must hold 4 pounds in CMP EIC matches, though I can't recall if there are any revolvers left on the approved list any more.  

3.6.  Any .45 Caliber Semi-automatic Pistol or Revolver – The .45 caliber pistol or revolver, as described below shall be used in .45 Caliber Precision Pistol matches. Any .45 caliber semi-automatic pistol or revolver; barrel length, including cylinders, not more than 10 inches, trigger pull for revolvers not less than 2 1/2 pounds, .45 caliber semi-automatic pistol trigger pull not less than 3 1/2 pounds.

There are no revolvers on the approved “Service Pistol” list. I have personally lobbied the CMP to allow it and was denied.

Question from above.  The text in 3.3 DR says, "The revolver must be capable of chambering and firing a 158- grain round nose or Semi-Wadcutter .38 Special cartridge. It must be a factory manufactured revolver..."  


Does being capable also mean the shooter must USE a 158 grain round or SWC .38 Special cartridge?  Or just have a pistol CAPABLE of shooting one?  Which would allow use of 148 gr HBWC if either work in the same gun?

That's the equipment requirement. A few paragraphs later are the ammunition requirements.  

(e) Ammunition- Any safe .38 caliber ammunition using the 158 grain round nose or Semi-Wadcutter bullet only.
