Welcome To Pinnacle High Performance!


Currently taking in all revolver work with fast turnaround!!!



Pinnacle High Performance is a truly custom pistolsmith shop. This one-man shop is operated by owner and pistolsmith Mark Hartshorne. Specializing in custom Revolvers, all work is performed to your needs, requirements, and specifications after thorough consultation.

I encourage you to call and discuss any custom work with me over the phone. This will give you faster and more detailed answers to any questions you may have. Please refrain from sending long drawn out emails requiring “novel” length answers.
Monday thru Friday…9am -4pm est. 610-285-4392.

“REPUTATION IS EVERYTHING” We’ve all been there. You pay for a job and the end result just doesn’t live up to your standards or expectations. It’s not done right and the quality is below par. At Pinnacle High Performance It’s about doing the job right because it’s the right thing to do. It’s about taking pride in your work and honoring your commitments to others. Reputation “is” everything!

Work time “estimates” are exactly that! This is an estimated time frame given at the time of your order. Due to the nature of precision pistolsmithing in a one-man shop I will not compromise the quality of work and the promise of personal undivided attention to any client in order to meet a projected time frame. This means I will not rush any projects that came in before your order, and I will not rush your custom project in order to meet a deadline for a project that came in after yours. Some projects are finished early; most are on time, and some orders run past the estimated time frame. Time frame estimating is not an exact science, especially those requiring truly custom work.

*Pinnacle High Performance is a Revolver Specialty Shop!
