The '''M20/Personal Defense Weapon''' ('''M20/PDW''') is a submachine gun produced by [[Misriah Armory]] and issued to [[United Nations Space Command]] service personnel.{{Ref/Reuse|universe}}{{Ref/Reuse|Enc22}}{{Ref/Reuse|REQ}} The M20 serves as a replacement for the [[M7 SMG]] in the [[Post-Covenant War conflicts|post-Covenant war]] era. The weapon is issued to UNSC vehicle and aircraft crews, security personnel, and [[Spartan]]s who expect to encounter close-quarters combat.{{Ref/Site|Id=CFLocke|URL=https://www.halowaypoint.com/en-us/news/canon-fodder-locke-load|Site=Halo Waypoint|Page=Canon Fodder - Locke & Load|D=08|M=11|Y=2020}}

==Overview==
===Design details===
The M20 is visually similar to its predecessor, though it differs in using a new high-velocity armor-piercing round that increases the amount of kinetic energy imparted to the target, specifically developed to counter the proliferation of military-grade armor among [[Insurrectionist]] cells and as a response to [[Covenant]] [[Energy shielding|energy shield]] technology.{{Ref/Reuse|universe}}{{Ref/Reuse|Enc22}} The weapon uses top-mounted magazines of cased [[5.7×28mm|5.7×28mm High Velocity, Armor Piercing (HV-AP)]] ammunition rather than the side-mounted magazines of caseless ammunition used by the M7. The top-mounted magazine offers an improved reload time and allows the weapon to be more open to customaisation and field-modification,{{Ref/Reuse|Enc22}} with the weapon compatible with nearly all UNSC [[weapon attachment]]s.{{Ref/Reuse|universe}}

By default, the M20 is equipped with a reflex [[CQB sight]], though as per above this can be swapped out.{{Ref/Reuse|Enc22}} The weapon's main frame features a retracting stock, folding foregrip, and a [[Smart-linking|smart-link]] electronics package to allow it to be used with any UNSC helmet. The weapon's lightweight construction allows it to be fired one-handed.{{Ref/Reuse|universe}} 

===Variants===
The M20's accessibility to production and customisation has opened the weapon up to having a large catalog of subvariants.{{Ref/Reuse|Enc22}} It is compatible with nearly all UNSC [[weapon attachment]]s.{{Ref/Reuse|universe}}

*'''[[Kinetic Bolts]]''': Augments knockback and damage against vehicles.
*'''[[Energy Bayonet]]''': Increases melee damage and range, allowing for a one-hit kill against normal opponents.

== Gameplay ==
{{Linkbox|gameplay=yes}}
=== Changes from M7 SMG in ''Halo 2: Anniversary'' ===
* Can now be zoomed in using the [[Spartan abilities#Smart Scope|Smart Scope]] to have its bullet spread reduced at the cost of added recoil.
* As of the November 2017 update, headshots with the M20 SMG now deal bonus damage on unshielded targets.
* Increased damage, killing in 19-20 rounds, (depending on the headshot bonus) instead of 25 rounds.
* Maximum reserve ammo increased from 180 to 360.
* Rate of fire is now 920 RPM.

=== Changes from ''Halo 5: Guardians'' to [[Halo Championship Series|HCS]] testing ===
* Maximum reserve ammo decreased to 300 (-14.3%).

=== Changes from HCS testing to [[Overtime]] ===
* Aim assist slightly decreased within effective range.
* Overall damage slightly reduced, including headshot damage.
* Accuracy slightly increased as the inner reticles no longer bloom outside of the outer circular reticle.

==Production notes==
The weapon's [[Halo Waypoint]] Universe article erroneously referred to the M20 PDW as firing the M7 SMG's [[5×23mm]] caseless ammunition.{{Ref/Reuse|universe}} However, the weapon is designed to eject spent shells - a behaviour which can be observed in-game. This discrepancy was corrected in the ''Halo Encyclopedia''.{{Ref/Reuse|Enc22}}

==Trivia==
The M20 bears similarity of both the [https://en.wikipedia.org/wiki/FN_P90 FN-P90]'s receiver-style magazine, and foresight, and the [https://en.wikipedia.org/wiki/Heckler_%26_Koch_MP7 MP7]'s frame.
