oe 3 Safety Features
As previously stated, the Department identified the need for an essential
safety feature that prohibited “pulling” the trigger to disassemble the firearm
for cleaning and preferred a firearm that did not require a special tool to
disassemble.
With officer safety being the most critical factor of selection, the Sig P320
stood above the other firearms with a “Take Down Safety system’ that:
«© ~=No Cleaning or Lubrication
os Sand / Dirt
o Water Immersion (5 Minutes)
= Low Light
« Reparability
« Ease of Care and Maintenance
s Ergonomics (Subjective)
s Design
e Ease of Operation and Use
° Access and Efficiency of Controls
«Trigger Efficiency
s Perceived Recoil
c Assembly/Disassembly
« Attitudes (ease of operation a differing angles)
® Cost per unit with manufacturer trade-in allowance and incentives
Test Criteria
Department Armorers, Firearms Instructors and End Users conducted a
| comparative evaluation of the sample weapons provided by FN, Glock, Sig
| Sauer and Smith & Wesson against the following criteria.
ANS! / SAAMI 2299.3-1993. Voluntary Industry Performance Standards
for Pressure and Velocity of Centerfire Pistol and Revolver Ammunition
for the Use of Commercial Manufacturers.
~~ 1 Sauer Model P320 Full size and Compact, and the Smith & Wesson Model
= | M&P9 and Model M&P9 Compact.
FNS-9 GLOCK 17
SIG P320 S&W MP9
Acceptance of Specialized Test Documentation
The FTU accepted manufacturer documentation of Specialized Test results,
these tests comply with industry standards for Law Enforcement firearms and
ensure minimum safety features and reliability during standard and abusive
handling.
Overview
ee i Test & Evaluation (T&E)
DPS conducted a comparative evaluation following specific T&E procedures
| and protocols. The T&E assessed firearm performance of four (4) models (see
» +| T&E Results), testing features and function to obtain quantitative and qualitative
“| data relevant to reliability, accuracy, ease of operation, safety, care and
“4 maintenance, and costs.

Conclusion
It is the recommendation of the Professional Standards Bureau that the Sig Sauer P320 in 9mm be
selected as the issue handgun of the Nashua Police Department during the next replacement cycle.
This firearm and ammunition recommendation is based on in house testing by Firearms Training Unit
officers as well as officers from the various divisions. The opinions developed in house are further
supported by research mentioned previously.
Respectfully Submitted
Captain Eric Nordengren
e Handgun stopping power is simply a myth
e The single most important factor in effectively wounding a human target is to have
penetration to a scientifically valid depth (FBI uses 12 to18 inches)
* 9mm Luger now offers select projectiles which are, under identical testing conditions
are outperforming the premium line .40S&W projectiles.
e 9mm Luger offers higher magazine capacities, less recoil, lower cost (both in
ammunition and wear on the weapons) and higher functional reliability rates.
P320 grip modules
The one trigger assembly pictured above can be utilized in any of the three grip module sizes, and
even across different calibers. The latter not being a need of the Nashua Police department at this
time.
