A few of weeks ago I published an article/video detailing the appearance of Swedish Carl Gustaf m/45 9x19mm submachine guns in Ukraine. One notable feature of the guns was that their configuration appeared to sit somewhere between the m/45A and the m/45B.
In the absence of clearer information I referred to these as m/45Bs, the most common variant and one which has the defining fixed magazine housing rather than the earlier removable magazine well seen on the m/45A. The fixed magazine well is an upgrade which was made before the later m/45B refit. It seems that there was some fluidity to how the upgrades were carried out which has led to gun with a mix of features.
From Swedish sources I’ve spoken to many of the m/45s seen in the imagery from Ukraine are early spec guns (m/45As) which may have been in storage and were not refit to the m/45B pattern. The m/45B refit was partially necessitated by the need to add an additional retention method to hold the receiver end-cap in place. Some sources suggest this was due to a type of training ammunition then in use, others point to it being simply extra security.
Working theories explaining the configuration of the guns seen in Ukraine include: that they are m/45A configuration guns which had been in storage and were retrofitted after the training ammunition left service and the additional end cap retention was no longer needed, so this change to the guns was omitted. As mentioned earlier, another reason may be that these are m/45As which had the magazine well upgrade but were placed in store or transferred before the broader m/45B upgrade was carried out.
As discussed in the initial video, it is thought that Estonia is a likely source for these guns as they received some of these guns in the 1990s and these m/45s have then subsequently been sent to Ukraine. Regardless of origin country the result is guns which do not have the additional end cap retention catch nor the green finish of the Swedish Army’s m/45B. They all feature the fixed magazine housing but there is also a mix of larger (earlier A guns) and smaller (later B guns) perforations in the barrel shrouds.
Since the last video a couple of other sources showing the m/45 in Ukraine were shared with me. Including this image of a Ukrainian combatant with a Swedish K which has the smaller barrel shroud holes. On 10 February a Daily Mail report, featured Thunder Company, an element with the 41st Mechanised Brigade. Members of the company show journalist Richard Pendlebury an m/45 that is in their inventory. The company’s deputy commander describes it as a ‘museum piece’. Both guns appear to be of the same configuration generally seen in Ukraine. On 4 March, another short video of a Ukrainian combatant firing an m/45 at what appears to be a range was shared. It’s unclear when or where the video was filmed.
