The image that Jon provided is older and doesn't show the important sentence added to rule 11 for EPFT "Elevation and windage adjustment turret clicking is allowed." Bear in mind that these are the rules used at Ron Robinson's matches. They may do things differently in AZ or elsewhere. Ron also specifies two classes, the only difference being sticks being allowed.
Here are the most recent EPFT rules I have:
2023 TEXtreme Pistol Field Target Rules
1. Air pistols only. The maximum caliber allowed is .25.
2. Muzzle energy is limited to a maximum of 20 foot-pounds.
3. Barrel length including shroud and muzzle attachments is limited to 15 inches. Barrel
length is measured from the tip of the barrel or muzzle attachment to the breech-face.
4. Fore-end depth is limited to a maximum of 3 inches, as measured from the center-
line of the bore to the lowest part of the gun forward of the trigger guard.
5. Attached cylinders at the rear of the pistol are not allowed.
6. Overall length including any attachments cannot exceed 25 inches.
7. No shooting jackets, slings, harnesses, or other bodily supports. Clothing or
shooting gloves worn by the shooter must not restrict hand or body movement.
8. Unattached shooting sticks, monopods and bipods are allowed. No tripods allowed.
9. Kneepads may not exceed 1 inch in thickness.
10. Sandbags, knee risers, and butt stocks are not allowed.
11. Scope maximum magnification is 12X. Variable scopes capable of greater than 12X
are allowed, but must be set to no higher than a 12X factory marking. Absent a 12X
factory marking, scopes must be set no higher than the next lower factory marking.
Elevation and windage adjustment turret clicking is allowed.
12. Bum-bags and seats are allowed that allow no form of arm or hand support.
13. Time limits may be enforced.
14. Any shooting position is allowed so long as the pistol is fully supported only by the
competitor and a monopod, bipod, or natural vegetation. Hangy-tanks are not allowed.
15. Target distances may be anywhere between 10 and 55 yards.
16. Kill zone sizes shall measure no less than .5”, no larger than 4”, and may be of any
shape.
17. Forced Standing Shots- Other than an unattached monopod, bipod, or natural rest
(trees, limbs, etc.), pistols are held solely by the hands, and may not contact the arms
or any other part of the body.
18. Light eyecup contact with the face is permitted.
19. Classes- There will be at least one class per match. Other classes may be added
as needed to accommodate at least three shooters in a given match.
Current TEXtreme PFT classes are: A) Pistolero Class: Rules as defined above.
B) Bandito Class: No shooting sticks, monopods or bipods allowed.
20. Pistol Rear Attachments- Allowed: Rear-mounted Power Adjuster. Reasoning: A
power adjuster is an integral part of the gun that does not provide additional support.
Not Allowed: Rear-mounted air cylinders or buffer tubes to fit a butt stock. Reasoning:
May provide additional support and weight ballast behind the grip of the gun.
